Assume a flight capacity is 100 seats and there are three nested fare classes 1, 2 and 3 from the highest to lowest fares. The optimal protection levels for classes 1 and 2 are:
Protection 1= 20
Protection 2= 50
Which of the following choices are correct?
a. Bkg Limits for classes 3, 2, 1 in the same order = 50, 70, 100
b. Bkg Limits for classes 3, 2, 1 in the same order = 30, 50, 20
c. Bkg Limits for classes 3, 2, 1 in the same order = 50, 20, 30
d. Bkg Limits for classes 3, 2, 1 in the same order 30, 80, 100

Answers

Answer 1

The correct choice for the booking limits for classes 3, 2, and 1, in the given order, is option (c): 50, 20, 30.

The booking limits determine the maximum number of seats allocated to each fare class. In this case, the optimal protection levels for classes 1 and 2 are given as Protection 1 = 20 and Protection 2 = 50. The booking limits should be set in a way that satisfies these protection levels while considering the total flight capacity of 100 seats. Since Protection 1 is 20, it means that class 1 should have a minimum of 20 seats reserved. Therefore, the booking limit for class 1 should be 20.

For Protection 2, which is 50, it indicates that classes 1 and 2 combined should have a minimum of 50 seats reserved. Since class 1 has already reserved 20 seats, the remaining 30 seats should be allocated to class 2. Therefore, the booking limit for class 2 should be 30. The remaining seats (100 - 20 - 30 = 50) are allocated to class 3. Therefore, the booking limit for class 3 should be 50. Thus, the correct choice for the booking limits for classes 3, 2, and 1, in the given order, is option (c): 50, 20, 30.

Suppose that during the next year real GDP rises and the nation's price level rises. According to the aggregate demand aggregate supply model, this could be caused by a rise in labor productivity. O a rise in the price of oil. O an increase in government spending. O an increase in taxes.

Answers

A rise in labor productivity can lead to a rise in real GDP and the nation's price level, while other factors such as an increase in government spending and taxes can cause a decrease in real GDP and the nation's price level.  The correct option is A.

Aggregate Demand (AD) and Aggregate Supply (AS) is an economic model that shows how the economy interacts with various macroeconomic factors. When there is a rise in real GDP along with a rise in the nation's price level, this is an indication of economic growth in the nation. It is believed that there are several factors responsible for this growth. Out of these factors, one of the factors is a rise in labor productivity. Hence, the option A is correct.

An increase in labor productivity implies that the production of goods and services increases, which leads to a higher supply of goods and services in the market. This, in turn, leads to an increase in GDP. An increase in productivity also lowers the production cost, leading to a decrease in prices.

However, this is only possible when the increase in productivity is relatively high, compared to the increase in prices. It is also essential to note that the relationship between AD and AS is dynamic, as changes in one factor lead to a ripple effect on the other. The correct option is A.

Answers

Although monopoly has lower output than competition, the level of output is not efficient: False This statement is false since, under a monopoly, the price is higher than in a competitive market, which causes customers to buy less. A monopolist might produce less than a competitive market.

Which implies that there is less efficiency because monopoly can increase prices and restrict output.2. In the long run, a monopolist charges the same price as a perfectly competitive firm: False A monopolist is characterized by market power; it can increase prices by reducing output to increase profit. A perfect competition firm sells identical goods at identical prices; the demand curve for a competitive market is horizontal.

For a monopolist, the demand curve is downward-sloping, meaning that there is a negative correlation between the price of a good and the amount demanded. As a result, a monopolist would charge a higher price than a perfectly competitive firm would. Hence, the given statement is false.

(c) How does σ1,2 compare to a Cobb-Douglas function? What does this mean? (2 pts)
(d) Solve for an interpret the local returns to scale for the short-run production function.

Answers

(a) Production function is strongly separable as it can be represented as f(z1,z2,z3) = h(z1) + g(z2) + q(z3), where h(z1) = 10z−41, g(z2) = 10z−42, and q(z3) = 10(1 + z−43)−1.

(b) In the short-run version of the function where the amount of plastic is fixed (z3 = 1), the production function can be represented as

f(z1,z2) = 10(1 + z−41 z−42)−1.

The elasticity of substitution for inputs 1 and 2 can be calculated as

σ1,2 = (z−41/z−42)(∂f/∂z1)(∂z2/∂f) = z−41z−42(1 + z−41z−42)−2.

When σ1,2 > 1, it means that the inputs are substitutes, and when σ1,2 < 1, it means that the inputs are complements. Here, σ1,2 = (z−41z−42)(1 + z−41z−42)−2 < 1,

which means that the inputs are complements. The Cobb-Douglas production function has a constant elasticity of substitution equal to 1, so σ1,2 < 1 means that the motorcycle production function exhibits less substitutability than the Cobb-Douglas function.

(d)The local returns to scale for the short-run production function can be calculated as

λ = ∑i=1n (zi/∂f/∂zi) (∂f/∂z0),

which gives λ = 10(1 + z−41z−42)−2, which is less than 1, indicating decreasing returns to scale.

Assume a proposed project under consideration by the James River Co. requires $28,900 in fixed assets. The firm plans to ignore bonus depreciation and instead apply straight-line depreciation to zero over the asset's 6-year life. An aftertax salvage value of $5,400 is expected. The project will produce an annual operating cash flow of $7,300 and will require net working capital of $500 initially plus an additional $500 in Year 3. Net working capital will be restored to its original level when the project ends at the end of Year 6. The tax rate is 21 percent and the required rate of return is 14 percent. What is the net present value of this project?

Answers

To calculate the net present value (NPV) of the project, we need to calculate the present value (PV) of the project's cash flows and compare it to the initial investment. The formula for NPV is:

NPV = PV of Cash Flows - Initial Investment

Let's calculate the PV of the cash flows:

Year 0:

Initial Investment = -$28,900 (outflow)

Years 1-6:

Operating Cash Flow = $7,300 (inflow)

Year 6:

Salvage Value = $5,400 (inflow)

Net Working Capital:

Year 0: -$500 (outflow)

Year 3: -$500 (outflow)

Year 6: +$500 (inflow)

Using a required rate of return of 14% and a tax rate of 21%, we can calculate the PV of the cash flows using the following formula:

PV = CF / (1 + r)^n

Where CF is the cash flow, r is the discount rate, and n is the time period.

Calculating the PV of the cash flows:

Year 0:

PV of Initial Investment = -$28,900 / (1 + 0.14)^0 = -$28,900

Years 1-6:

PV of Operating Cash Flow = $7,300 / (1 + 0.14)^1 + $7,300 / (1 + 0.14)^2 + $7,300 / (1 + 0.14)^3 + $7,300 / (1 + 0.14)^4 + $7,300 / (1 + 0.14)^5 + $7,300 / (1 + 0.14)^6 = $35,254.27

Year 6:

PV of Salvage Value = $5,400 / (1 + 0.14)^6 = $2,357.94

Net Working Capital:

PV of Net Working Capital = -$500 / (1 + 0.14)^0 + -$500 / (1 + 0.14)^3 + $500 / (1 + 0.14)^6 = -$1,089.50

Now, we can calculate the NPV:

NPV = PV of Cash Flows - Initial Investment

= ($35,254.27 + $2,357.94 - $1,089.50) - $28,900

= $8,622.71 - $28,900

= -$20,277.29

The net present value (NPV) of this project is -$20,277.29. Since the NPV is negative, it indicates that the project is expected to generate a return lower than the required rate of return of 14%. Therefore, based on NPV analysis, the project may not be considered favorable for investment.

[4 marks] (d) Now assume that the underlying stock has a volatility of 35% and the (continuously compounded) risk-free rate is given by r= 1%. What is the price of the note in the Black-Scholes-Merton model?

Answers

The Accelerated Return Note is a financial instrument whose payoffs at maturity depend on the value of an underlying stock and a notional value N. In this case, assuming no dividends are paid, if the ending value of the underlying stock is equal to or below the starting value, the note will pay N times the ending value minus the starting value.

However, if the ending value is greater than the starting value, the payoff is determined by the minimum of two options: the square root of the ending value times 1.2 or N plus twice the starting value.

To draw the payoff diagram for the Accelerated Return Note, let's assume N = 100 and the initial value of the underlying stock is $50. The maturity of the note is one year. If the ending value of the stock is below or equal to $50, the payoff is N times the ending value minus the starting value, which in this case is 100 times the ending value minus 50. However, if the ending value is above $50, the payoff is the minimum of two options: the square root of the ending value times 1.2 or N plus twice the starting value, which is 100 plus 2 times 50.

Now, let's consider the replication of the payoff using only European calls, which are options that give the holder the right to buy the underlying asset at a predetermined price. To replicate the payoff of the Accelerated Return Note, we would need a combination of long and short European calls with different strike prices. By carefully selecting the strike prices and the number of options, we can create a portfolio that replicates the note's payoff profile.

On the other hand, if only European puts are available, which are options that give the holder the right to sell the underlying asset at a predetermined price, we would need a combination of long and short European puts with different strike prices to replicate the note's payoff. Similar to the replication using European calls, by strategically choosing the strike prices and the number of options, we can construct a portfolio that mimics the payoff of the Accelerated Return Note.

To determine the price of the note in the Black-Scholes-Merton model, we need to consider the volatility of the underlying stock, which is given as 35%, and the risk-free rate, which is 1% (continuously compounded). Applying the Black-Scholes-Merton formula, we can calculate the price of the note by considering the expected value of the discounted payoff at maturity, taking into account the volatility and risk-free rate. The exact calculation would require the specific values of the underlying stock at maturity and other parameters, such as the strike prices of the options used in the replication.

Answers

The new deadweight loss at the higher tax rate is anticipated to be greater than $100, but less than $200, according to option a.

When the tax is raised from $0.10 to $0.20 per unit, the deadweight loss is predicted to rise. We may anticipate this to be the case since the higher tax rate increases the wedge between the cost to buyers and the price received by sellers, making it more expensive to buy and sell goods. The new deadweight loss at the higher tax rate is anticipated to be greater than $100, but less than $200, according to option a. A deadweight loss arises when the social benefit of a good or service is less than the total cost to society of producing and distributing that good or service. This implies that if a tax is placed on a good or service, the reduction in demand due to the tax causes a drop in the quantity of the good or service traded and, as a result, a deadweight loss arises.

1. The revenue recognized in April under cash-basis accounting is $16,700.

2. The revenue recognized in April under accrual-basis accounting is $39,530.

Revenue recognized in April under cash-basis accounting is $16,700. The reason is, cash-basis accounting records the revenue when the cash is received. Therefore, the revenue recognized from selling 8,350 CDs for cash at $2.00 each is $16,700.Revenue recognized in April under accrual-basis accounting is $39,530. The reason is, accrual-basis accounting records the revenue when it is earned, not when the cash is received. Therefore, the revenue recognized from selling 8,350 CDs on cash at $2.00 each is $16,700, and from selling 14,730 CDs on credit at $2.00 each is $29,460.

Also, $9,850 is the collection of credit sales made in April, so these sales are recorded in April. But, $10,300 is the collection of credit sales made in the previous month, so these sales are recorded in the previous month. Therefore, the total revenue recognized in April under accrual-basis accounting is $16,700 + $29,460 + $9,850 = $39,530.

Answers

Joint allocation methods are used to distribute joint costs among multiple products produced in the same process. Joint costs are the costs incurred in the production of these products until the split-off point. After the split-off point, the joint products are further processed into individual products. Joint cost allocation methods help assign these costs to the resulting products. The correct answer is option C. the sales value at the split−off method is the best measure of benefits received.

However, it is not true that the sales value at the split-off method is the best measure of benefits received.

The sales value at the split-off method allocates joint costs based on the sales value of the products at the split-off point.

While this method is one approach to allocate costs, it may not necessarily reflect the actual benefits received from the joint products.

Other allocation methods, such as the net realizable value method or the physical units method, may be more appropriate depending on the circumstances.

Therefore, it is important to select a joint cost allocation method that aligns with the specific goals and requirements of the organization, taking into consideration factors such as market conditions, product values, and overall cost management objectives.

Therefore, the correct answer is option C. the sales value at the split−off method is the best measure of benefits received.

The three commonly used strategies are horizontal fragmentation, vertical fragmentation, and hybrid fragmentation. Each strategy offers unique approaches to partitioning data effectively.

Horizontal Fragmentation:

Horizontal fragmentation divides a table's rows into subsets based on a specific condition or attribute value. Each subset contains a portion of the rows that satisfy the condition, allowing for more focused data retrieval. Here are examples of horizontal fragmentation that differ from the book:

a. An e-commerce website:

The customer data is horizontally fragmented based on customer behavior, such as frequent shoppers, new customers, and seasonal buyers. Each subset is stored separately, facilitating targeted marketing campaigns and personalized recommendations.

b. Healthcare system:

Patient records are horizontally fragmented based on medical conditions, such as diabetes, hypertension, and allergies. This fragmentation enables efficient management and analysis of specific patient groups.

Vertical Fragmentation:

Vertical fragmentation divides a table's columns into subsets, grouping related attributes together. This strategy helps optimize storage and retrieval of specific data subsets. Here are examples of vertical fragmentation that differ from the book:

a. HR management system:

Employee data is vertically fragmented based on security requirements. Sensitive personal information, such as social security numbers and addresses, is stored in a separate subset with restricted access, while other job-related attributes are stored in another subset.

b. Logistics system:

Product information is vertically fragmented based on different distribution channels. One subset may contain attributes relevant to online sales, while another subset stores attributes specific to retail store distribution.

Hybrid Fragmentation:

Hybrid fragmentation combines elements of horizontal and vertical fragmentation strategies, providing a flexible and efficient approach to data partitioning. Here are examples of hybrid fragmentation that differ from the book:

a. Social media platform:

User data is horizontally fragmented based on geographic regions and vertically fragmented based on user interests and preferences. This fragmentation allows targeted content delivery while ensuring data is stored in a distributed and optimized manner.

b. Manufacturing system:

Product data is horizontally fragmented based on different production lines and vertically fragmented based on various manufacturing stages. This fragmentation enables efficient analysis, monitoring, and optimization of the manufacturing process.

Conclusion:

Data fragmentation strategies, including horizontal, vertical, and hybrid fragmentation, are valuable tools in database design. They allow for efficient storage, retrieval, and management of large datasets. The examples provided demonstrate how these strategies can be applied in different contexts, showcasing their flexibility and effectiveness in meeting specific data organization requirements.

c) Consider a bond with three years to maturity with a face value of $F. At the end of each year it pays a cash coupon of $C. Denote its yield to maturity by y. i. You buy the bond today for a price of $P, and sell it in one year (just after the payment of the coupon) for $P₁. If the yield to maturity does not change over time, write down expressions for P, and for P, in terms of C, F and y. [2 marks] ii. Define the return from holding the bond for that year in the normal fashion (i.e. the return is equal to the sum of its change in price over the period and any end of period cash payments, all divided by the initial price). Show how this return is related to the bond's yield to maturity. [4 marks] iii. Based on your preceding answer, discuss when yield to maturities are likely to be decent indicators of the returns from holding bond positions. [3 marks]

Answers

To calculate the bond price today (P), we discount the future cash flows (coupon payments and face value) using the yield to maturity (y) as the discount rate. The bond price after one year (P₁) can be calculated by discounting the remaining cash flows (coupon payments and face value) at the same yield to maturity (y).

P = (C / (1 + y)) + (C / (1 + y)²) + (C / (1 + y)³) + (F / (1 + y)³)

P₁ = (C / (1 + y)) + (C / (1 + y)²) + (F / (1 + y)²)

The return from holding the bond for one year can be calculated as the change in price (P₁ - P) plus any end-of-period cash payments (coupon received at the end of the year), divided by the initial price (P).

Return = ((P₁ - P) + C) / P

The bond's yield to maturity (y) is related to the return through the equation:

Return = (1 + y) - 1

Yield to maturities are likely to be decent indicators of the returns from holding bond positions when the yield to maturity remains constant over time. If the yield to maturity changes during the holding period, the actual returns may deviate from the yield to maturity. The relationship between yield to maturity and return assumes that the bond is held until maturity and all coupons are reinvested at the yield to maturity rate. However, in the real world, market conditions, interest rate changes, and other factors can affect bond prices and returns. Therefore, while yield to maturity provides a useful measure of expected return, it may not always accurately predict actual returns from holding bond positions.

The Terrence Co. manufactures two products, Baubles and Trinkets. The following are projections for the coming year: Baubles 11,000 units Trinkets 5,500 units Sales $11,000 $11,000 Costs: Fixed $2,400 $7,680 Variable 4,400 6,800 2,200 9,880 Income before taxes $ 4,200 $ 1,120 How many Baubles will be sold at the break-even point, assuming that the facilities are jointly used with the sales mix remaining constant?

Answers

At the break-even point, approximately 1,000 Baubles will be sold, assuming that the facilities are jointly used and the sales mix remains constant.

The break-even point occurs when the income before taxes is zero, indicating that the company is neither making a profit nor incurring a loss. In this case, we need to find the sales volume of Baubles at which the income before taxes becomes zero.

To calculate the break-even point, we subtract the total fixed costs from the total variable costs for Baubles. From the given information, the fixed costs for Baubles are $2,400 and the variable costs are $4,400. Therefore, the total costs for Baubles at the break-even point would be $2,400 + $4,400 = $6,800.

Next, we divide the total fixed costs by the contribution margin per unit for Baubles. The contribution margin per unit is the selling price per unit minus the variable cost per unit. From the given information, the selling price for Baubles is $11,000 and the variable cost per unit is $4,400. Therefore, the contribution margin per unit for Baubles is $11,000 - $4,400 = $6,600.

Dividing the total fixed costs of $6,800 by the contribution margin per unit of $6,600, we find that approximately 1 Bauble will be sold at the break-even point.

What is the depreciation charge of an equipment purchased four years ago for $120,000, a salvage value of $20,000, and a expected life of 4 years if it is depreciated using a straight line method?
a. $25,000
b. $11,428.60
c. $20,000
d. $14,285.71

Answers

The depreciation charge of the equipment, which was purchased four years ago for $120,000, has a salvage value of $20,000, and is depreciated using the straight-line method, is $25,000.  Option a) $25,000 is the correct answer.

The straight-line method of depreciation evenly allocates the cost of an asset over its expected life. To calculate the depreciation charge, we need to determine the depreciable base, which is the original cost minus the salvage value.

Given that the equipment was purchased for $120,000 and has a salvage value of $20,000, the depreciable base is $120,000 - $20,000 = $100,000.

Since the equipment has an expected life of 4 years, the annual depreciation charge is calculated by dividing the depreciable base by the expected life: $100,000 / 4 = $25,000.

Therefore, the depreciation charge for the equipment, using the straight-line method, is $25,000.

In the given scenario, a company uses a predetermined overhead rate (POHR) of $14.00 per direct labor hour. The company provides the following data for job A-500:Direct materials $230Direct labor $108Total manufacturing cost assigned to Job.

A-500The manufacturing overhead rate can be computed using the given information. Since POHR is $14.00 per direct labor hour and direct labor is $108. Therefore, direct labor hours are:Direct Labor Hours = Direct Labor Costs ÷ Direct Labor Rate= $108 ÷ $20= 5.4 HoursNow, we can calculate the total manufacturing cost assigned to job A-500 using the formula.

Total Manufacturing Costs = Direct Materials + Direct Labor + Manufacturing Overhead= $230 + $108 + (5.4 × $14.00)= $230 + $108 + $75.60= $413.60Average cost assigned to each unit included in the jobIf job A-500 consists of 40 units, we can find the average cost assigned to each unit by dividing total manufacturing costs by the number of units.Total Cost per Unit = Total Manufacturing Cost ÷ Number of Units= $413.60 ÷ 40= $10.34 (rounded to two decimal places)Therefore, the total manufacturing cost assigned to Job A-500 is $413.60, and the average cost assigned to each unit included in the job is $10.34.It's a method for measuring forecast accuracy.The MAD method 1 = 1.75 thousand gallons.The absolute deviation based on the forecast developed using Method 1 adds to 7 thousand gallons.The Mean Squared Error (MSE) is calculated by averaging the square of the difference between the actual and forecasted values.

Is the trade balance same as the current account balance? Why
does the financial account balance not always equal the current
plus capital account balance?

Answers

The trade balance and the current account balance are not the same. While both terms relate to a country's international transactions, they represent different aspects of the overall economic picture.

The trade balance refers to the difference between the value of a country's exports and imports of goods. It is commonly referred to as the balance of trade. A positive trade balance, also known as a trade surplus, occurs when a country's exports exceed its imports, indicating that it is exporting more goods than it is importing. Conversely, a negative trade balance, or a trade deficit, means that a country is importing more goods than it is exporting.

On the other hand, the current account balance is a broader measure that includes not only the trade balance but also other international transactions. In addition to the trade of goods, the current account takes into account the trade of services, income from investments and assets, and transfers such as foreign aid or remittances. Therefore, the current account balance provides a more comprehensive view of a country's overall economic interactions with the rest of the world.

It's important to note that the trade balance is just one component of the current account balance. While a country's trade balance can have a significant impact on its current account balance, other factors such as services trade, income from investments, and transfers also contribute to the overall current account balance. Therefore, it is possible for a country to have a trade deficit but still maintain a positive current account balance if the surplus from other components offsets the trade deficit.

traditionally, large companies distribute excess inventory through _____.

Answers

Traditionally, large companies distribute excess inventory through methods such as clearance sales, liquidation, or wholesale channels.

When large companies have excess inventory, they typically employ various strategies to distribute and sell these surplus goods. One common method is to hold clearance sales. This involves offering discounts and promotions on the excess inventory to attract customers and encourage them to make purchases. Clearance sales can take place in physical stores or online platforms, allowing companies to quickly offload surplus goods. Liquidation is another approach used by large companies to distribute excess inventory. In this process, the company sells the surplus goods to liquidators or wholesalers at discounted prices. The liquidators then sell the products through their own channels, such as discount stores or online marketplaces.

Large companies may also opt to distribute excess inventory through wholesale channels. They may sell the surplus goods in bulk quantities to wholesalers, who then distribute them to retailers or other businesses. Wholesale channels provide an opportunity for companies to sell large volumes of excess inventory efficiently. These traditional methods of distribution help large companies manage their excess inventory by finding ways to sell it and recoup some of the invested capital. By employing clearance sales, liquidation, or wholesale channels, companies aim to minimize losses and make room for new inventory.

Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. 20 Demand 16 Supply Supply mand 4 16 24 32 40 QUANTITY (Millions of bushels)

Answers

The shock of unusually good weather, which increases soybean production per acre of land, would affect the market for soybeans by shifting the supply curve to the right.

When the weather improves and enables soybean producers to generate more soybeans per acre of land, the supply of soybeans in the market will increase. This is because producers can now offer a higher quantity of soybeans at each price level.

The shift in the supply curve can be visually represented by dragging the supply curve to the right, indicating a higher quantity supplied at each price level.

As a result, the new supply curve will intersect the original demand curve at a higher equilibrium quantity and a lower equilibrium price.

The shock of unusually good weather in the soybean market leads to an increase in the supply of soybeans. This, in turn, affects the equilibrium price and quantity in the market.

The quantity of soybeans supplied will increase, leading to a higher equilibrium quantity, while the equilibrium price will decrease.

It's important to note that this analysis assumes ceteris paribus, meaning it only considers the impact of the weather shock on the supply of soybeans.

Inflation, output and unemployment are fixed e. None of these

Answers

The statement "Even with the power to change interest rates, the Fed is unable to directly impact inflation, output, or unemployment" is incorrect. The Federal Reserve's ability to change interest rates does have an impact on inflation, output, and unemployment.

Option C, "Interest rates determine the opportunity cost of spending money today," is the correct answer.

The Federal Reserve, also known as the Fed, uses its control over interest rates to influence economic conditions.

By adjusting interest rates, the Fed can affect borrowing costs for businesses and individuals, which in turn impacts spending, investment, and consumption.

When the Fed lowers interest rates, it becomes cheaper to borrow money, stimulating spending and investment.

This increased economic activity can lead to higher output and employment levels.

Conversely, when the Fed raises interest rates, borrowing becomes more expensive, which can dampen spending and investment, potentially reducing inflationary pressures.

Inflation, output, and unemployment are not fixed; they are variables that respond to changes in the overall economic environment.

The Federal Reserve's monetary policy actions, including changes in interest rates, are designed to influence these variables and steer the economy towards desired outcomes.

Therefore, option e, "None of these," is incorrect. The Fed's ability to change interest rates provides a mechanism through which it can directly impact inflation, output, and unemployment, making options a, b, d, and e incorrect as well.

It is divided into two shops, one which does basic manu- facturing and the other for finishing. Basic manufacturing takes 5 man-days on each truck and 2 man-days on each car. Finishing takes 3 man-days for each truck or car. Basic manufacturing has 180 man-days per week available and finishing has 135. If the profits on a truck are $300 and $200 for a car. how many of each type of vehicle should the factory produce in order to maximize its profits? What is the maximum profit? Let 1 be the number of trucks produced and 2 the number of cars. Solve this graphically.
