The major advantage of a regular partnership or a corporation as a form of business organization is the fact that both offer their owners limited liability, whereas proprietorships do not. True False
Answer:
True
Explanation:
Some owners of a regular partnership (limited liability partnership) or a corporation (S-corporation) enjoy limited liability, unlike the owners of proprietorships, whose business liabilities and solvency are backed with the personal assets of the owners. The owners of a C-corporation enjoy full limited liability unless the corporate veil is lifted by the court, depending on prevailing circumstances.

A perfectly elastic supply curve is: Group of answer choices upward sloping to the right. vertical. horizontal. downward sloping to the left.
Answer:
vertical
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.
On January 1, 2024, an investor paid $261,000 for bonds with a face amount of $315,000. The contract rate of interest is 8% while the current market rate of interest is 10%. Using the effective interest method, how much interest income is recognized by the investor in 2025 (assume annual interest payments and amortization)
Answer:
$26,100
Explanation:
Calculation to determine how much interest income is recognized by the investor in 2025

Let plug in the formula
Interest income= $261,000*10%
Interest income= $26,100
Therefore the interest income that is recognized by the investor in 2025 will be $26,100

4. Which of the following situations typically would result from an appreciating U.S. dollar relative to the
Canadian dollar?
A. More Canadian tourists visit the U.S.
B. Canadians purchase more U.S. goods
C. Fewer American tourists visit Canada
D. Americans purchase more Canadian made products.
Answer:
D. Americans purchase more Canadian made products.
Explanation:
The situation that would typically result from an appreciating U.S. dollar relative to the Canadian dollar is "Americans purchase more Canadian made products."
When Americans purchase more Canadian-made products, the Canadian dollar will rise or appreciate against the U.S. dollar. This is based on the principle of trade balance, whereby the monetary value of a country's imports and exports are evaluated over a given period.
In this case, the monetary value of Canadian exports against the U.S. dollar will indicate a positive trade surplus, hence, the Canadian dollar or currency will appreciate against the U.S. dollar.

DW has an ending Retained Earnings balance of $51,600. If during the year DW paid dividends of $4,100 and had net income of $21,100, then what was the beginning Retained Earnings balance
Answer:
$34,600
Explanation:
The computation of beginning retained earnings balance is seen below:
But we know that;
Ending balance of retained earnings = Beginning balance of retained earnings + Net income - Dividend paid
$51,600 = Beginning retained earnings + $21,100 - $4,100
Beginning retained earnings = $51,600 - $21,100 + $4,100
Beginning retained earnings = $34,600

Discount rate = r = 13% = 0.13
Value of the preferred stock can be calculated using the perpetuity formula:
Value of the dividend = P = D/r = 120/0.13 = $923.08
Therefore the value of stock is $923.08
Assume your entry price for both long and short positions is $50 and you would like to set the reward-risk ratio (RRR) at 1.2. Calculate the profit and loss exit points for both long and short positions.
Answer:
Long Position
Profit exit point: sell limit= 8.33
Loss exit point= 41.66
Short Position
Lost exit point: buy stop= 58
Profit exit point:buy limit=40
Explanation:
Calculation to determine the profit and loss exit points for both long and short positions.
LONG POSITION profit and loss exit points
First step is to calculate the Profit exit point: sell limit
Profit exit point: sell limit=( 50x10% )/1.2
Profit exit point: sell limit=$10/1.2
Profit exit point: sell limit= 8.33
Now let calculate the Loss exit point
Loss exit point=50-8.33
Loss exit point= 41.66
SHORT POSITION profit and loss exit points
Lost exit point: buy stop=20%/x=1.2
Lost exit point: buy stop=20%/2
Lost exit point: buy stop=1.6
Lost exit point: buy stop= 50+(50x1.6)
Lost exit point: buy stop= 58
Now let calculate the Profit exit point:buy limit:
Profit exit point:buy limit=50-(50*.20)
Profit exit point:buy limit=40

An investment project has annual cash inflows of $4,200, $5,100, $6,300, and $5,500, and a discount rate of 15 percent. a. What is the discounted payback period for these cash flows if the initial cost is $6,900
Answer:
It will take 1 year and 307 days to cover the initial investment.
Explanation:
Giving the following information:
Initial investment= $6,900
Cash flows:
Cf1= $4,200
Cf2= $5,100
Cf3= $6,300
Cf4= $5,500
Discount rate= 15%
The payback period is the time required to cover the initial investment. We need to discount each cash flow.
Year 1= 4,200/1.15 - 6,900= -3,247.83
Year 2= 5,100/1.15^2 - 3,247.83= 608.50
To be more accurate:
(3,247.83 / 3,856.33)*365= 307 days
It will take 1 year and 307 days to cover the initial investment.

Assume that, on January 1, 2021, Matsui Co. paid $1,795,200 for its investment in 74,800 shares of Yankee Inc. Further, assume that Yankee has 220,000 total shares of stock issued. The book value and fair value of Yankee's identifiable net assets were both $440,000 at January 1, 2021. The following information pertains to Yankee during 2021:
Net income $240,000
Dividends declared and paid $72,000
Market price of common stock on 12/31/2016 $29/share
What amount would Matsui report in its year-end 2016 balance sheet for its investment in Yankee?
a. $1,608,000.
b. $1,368,000.
c. $1,329,600.
d. None of these answer choices is correct.
Answer: $1,852,320
Explanation:
First find out the proportion owned by Matsui.
= 74,800 shares / 220,000
= 34%
The investment at the end of the year is:
= Cost of investment + Shares of net income - Share of dividend
Share of income:
= Percentage ownership * Net income
= 34% * 240,000
= $81,600
Share of dividend:
= 34% * 72,000
= $24,480
Investment at end of year:
= 1,795,200 + 81,600 - 24,480
= $1,852,320

You are to make monthly deposits of $1,721 into a retirement account that pays 8 percent interest compounded monthly. If your first deposit will be made one month from now, how large will your retirement account be in 5 years?
Answer:
FV= $126,585.60
Explanation:
Giving the following information:
Monthly deposit (A)= $1,721
Interest rate (i)= 0.08/12= 0.0067
Number of periods (n)= 12*5= 60 months
To calculate the future value, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
FV= {1,721*[(1.0067^60) - 1]} / 0.0067
FV= $126,585.60
In 1 to 2 paragraphs, analyze how a person's ethics or values might affect his performance on the job
Answer:
In simple words, Individual workers' ethical convictions have an impact on team and department productivity as well as individual achievement. Being an ethical worker allows you to be a stronger team participant constantly contributing positively in group situations and just never impeding collective success.
Even though all individuals are important in and of themselves, ethical individuals can be more monetarily useful to their companies as well as more respected by their colleagues and competitors. Reflecting on workplace ethics may help you become a better employee, and it's a good thing to begin if you want to do the right thing all of the time.
Answer:
How can poor ethics devalue you as an asset on the team? Well, if you have poor moral standards and beliefs and what not, people can somewhat easily identify your personality as a negative trait. However if you're a good person with good values and spot on ethics, people will quickly realize that you're a good asset to have on the team.
Your energy, work ethic, and values also determine how good or bad your work ethic is.

Consider the following demand schedule: Price Quantity Demanded $25 20 $20 40 $15 60 $10 80 What is the price elasticity of demand between (using the arc formula) a) Price $25-$20 a) Price $20-$15 a) Price $15-$10
Answer:
3.05
1.38
0.725
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Arc elasticity of demand = midpoint change in quantity demanded / midpoint change in price
Midpoint change in quantity demanded = change in quantity demanded / average of both demands
Price $25-$20
change in quantity demanded = 40 - 20 = 20
average of both demands = (40 + 20) /2 = 30
Midpoint change in quantity demanded = 20/30 = 0.67
midpoint change in price = change in price / average of both price
change in price = $25 - $20 = $5
average of both price = ($25 + $20) / 2 = 22.5
Price $20-$15
change in quantity demanded = 60 - 40 = 20
average of both demands = (60 + 40) /2 = 50
Midpoint change in quantity demanded = 20/50 = 0.4
midpoint change in price = change in price / average of both price
change in price = $20 - $15 = $5
average of both price = ($15 + $20) / 2 = 17.5
midpoint change in price = 5 / 17.5 = 0.29
0.4/0.29 = 1.38
Price elasticity of demand = 0.67 / 0.22 = 3.05
change in quantity demanded = 80 - 60 = 20
average of both demands = (80 + 60) /2 = 70
Midpoint change in quantity demanded = 20/70 = 0.29
midpoint change in price = change in price / average of both price
change in price = $15 - $10 = $5
average of both price = ($15 + $10) / 2 = 12.5
5/12.5 = 0.4
