The computation is shown below:
a. Holding period return would be
= Income + (End of Period Value - Initial Value) ÷ Initial Value
= 0 +($2,178 - $1,902) ÷ $1,902
= 0 + $276 ÷ $1,902
= 14.51%
b. The annual percentage rate is
For 3 months, the rate is 14.51%
Now
For 12 months, it is
= 14.51% ÷ 3 × 12
= 14.51 % × 4
= 58.04%
c. The effective annual rate is
= ( 1 + r ÷ m)^m - 1
= (1 + 58.04% ÷ 4)^4 - 1
= (1 + 0.5804 ÷ 4)^4 - 1
= (1 + 0.1451)^4 - 1
= (1.1451)^4 - 1
= 1.719387079 - 1
= 0.719387079 or 71.94%

Explanation:
A monopolist can sell 10,000 units at a price of $5 per unit. Lowering price to all buyers by $1 raises the quantity demanded by 1,000 units. What is the change in total revenue resulting from this price change?
Answer:
the revenue decreases by -$6000
Explanation:
The computation of the change in revenue is shown below:
Total revenue at Price is 5
Now total revenue is
= $5 × 10,000 units
= $50,000
Total revenue at Price is 4
Now Total Revenue is
= $4 × 11,000
= $44,000
Now the difference is
= $44,000 - $50,000
= -$6,000
Hence, the revenue decreases by -$6000

What are the annual social security withholding for an executive whose annual gross earnings are $98,485?
Answer:
$6,106.07
Explanation:
Calculation for the annual Social security withholding
Based on the information given the annual gross earnings are the amount of $98,485 which is lower than the taxable maximum of the amount of $137,700 in 2020 as well as the amount of $142,800 in 2021 which means that the annual social security withholding will be :
Using this formula
Annual Social security withholding =6.2%*Annual gross earnings that is subject to a taxable maximum
Let plug in the formula
Annual Social security withholding= 6.2%*$98,485
Annual Social security withholding= $6,106.07
Therefore the Annual Social security withholding will be $6,106.07
Based on the following information, calculate the cost of goods sold and ending inventory using FIFO, LIFO, and weighted average assuming a perpetual inventory system is in place.
Beginning Balance - 90 units at $11
March 3 - Purchase 300 units for $15
April 4 - Sell 240 units for $28
June 30 - Purchase 250 units for $18
August 16 - Sell 180 units for $30
Answer:
Cost of Sales :
FIFO = $ 6,030
LIFO = $6,840
Weighted Average = $6,354.60
Ending Inventory :
FIFO = $4,176
LIFO = $3,150
Weighted Average = $3,636.60
Explanation:
FIFO
This method assumes that the first inventory purchased will be the first to be sold
Cost of Goods Sold :
90 units × $11 = $990
150 units × $15 = $2,250
150 units × $15 = $2,250
30 units × $18 = $540
Total = $ 6,030
Ending Inventory :
232 units × $18 = $4,176
LIFO
This method assumes that the last inventory purchased, will be the last to be sold
Cost of Sales :
240 units × $15 = $3,600
180 units × $18 = $3,240
Total = $6,840
Ending Inventory :
90 units × $11 = $ 990
60 units × $15 = $ 900
70 units × $18 = $ 1,260
Total = $3,150
Weighted Average
A new average cost per unit is calculated with every purchase made.
New Average Cost = (90 units × $11 + 300 units × $15) ÷ 390 units
= $14.08
Cost of Sale , April 4 = 240 units × $14.08
= $3,379.20
New Average Cost = (150 units × $14.08 + 250 units × $18.00) ÷ 400 units
= $16.53
Cost of Sale, Aug 16 = 180 units × $16.53
= $2,975.40
Total Cost of Sales = $3,379.20 + $2,975.40
= $6,354.60
Ending Inventory = 220 units × $16.53
= $3,636.60
Jennifer Creek is saving up for a new car. She wants to finance no more than $10,000 of the $26,000 estimated price in two years. She deposits $5,000 into a savings account now and will make monthly deposits for the next two years. If the savings account pays a nominal interest rate of 3% per year with monthly compounding, how much must she deposit each month?
Answer: $432.74
Explanation:
Since Jennifer wants to buy the car in the next two years and the car cost is $26000 and she wants to finance no more than $10,000, therefore she'll require ($26000 - $10000) = $16000.
In order for her to get $16000 for the next two years, she wants to deposit $5000 today and she'll make a month deposit which can be represented by A every month. The interest rate will be calculated as: 3%/12 = 0.03/12 = 0.0025 = 0.25% every month.
Therefore, the amount that she must deposit each month will be:
$5000(F/P,0.25%,24) + A(F/A, 0.25%, 24) = $16000
$5000(1.062) + A(24.703) = $16000
$5310 + 24.703A = $16000
24.703A = $16000 - $5310
24.703A = $10690
A = $10690/24.703
A = $432.74
The amount that she must deposit each month will be $432.74

If the growth rate of the money supply is 8%, velocity is constant, and real GDP grows at 4% per year on average, then the inflation rate will be _____%.If the growth rate of the money supply increases to 13%, velocity is constant, and real GDP grows at 2% per year on average, then the inflation rate will be _____%.If the growth rate of the money supply increases to 13%, velocity grows at 11%, and real GDP grows at 2% per year on average, then the inflation rate will be ______%.
Answer:
Explanation:
The formula to solve the question is:
∆M + ∆V = ∆P + ∆Y
where,
∆M = relation among money growth
∆V = changes in money velocity
P = change in prices
∆Y = change in real GDP
1. For question 1,
∆M = 8%, ∆V = 0, ∆Y = 4
∆M + ∆V = ∆P + ∆Y
8% + 0 = ∆P + 4%
∆P = 8% - 4%
Inflation rate = 4%
2. ∆M = 13%, ∆V = 0, ∆Y = 2%
∆M + ∆V = ∆P + ∆Y
13% + 0 = ∆P + 2%
∆P = 13% - 2%
∆P = 11%
Inflation rate = 11%
3. ∆M = 13, ∆V = 11, ∆Y = 2
∆M + ∆V = ∆P + ∆Y
13% + 11% = ∆P + 2%
∆P = 13% + 11% - 2%
∆P = 22%
Inflation rate = 22%

If a company increases its prices from $2 to $2.20, and its sales fall from 5 million units to 4.5 million units, using the midpoint method, what is the price elasticity of demand for this market?
a. 1
b. 1.5
c. 2
d. 0.5
Answer:
-1.10526
Explanation:
The computation of the price elasticity of demand is shown below:
Price elasticity of demand is
= (Change in quantity demanded ÷ average of quantity demanded) ÷ (Change in price ÷ average of price)
where,
q1 = 5
q2 = 4.5
p1 = $2
p2 = $2.2
So,
= {(4.5 - 5) ÷ (4.5 + 5) ÷ 2} ÷ {(2.2 - 2) ÷ (2.2 + 2) ÷ 2 }
= {-0.5 ÷ 4.75 } ÷ {0.2 ÷ 2.1 }
= -0.10526 ÷ 0.0952
= -1.10526

(Assume a month is 30 days)- 10 ships per month- 30 ships per month- 6 ships per month- 1/5 ships per month
Answer:
6 ships per month
Explanation:
30 ships are held for 150 days
[tex]30\ \text{ships}=150\ \text{days}[/tex]
[tex]1\ \text{day}=\dfrac{30}{150}\ \text{ships}[/tex]
[tex]1\ \text{day}=\dfrac{1}{5}\ \text{ships}[/tex]
[tex]30\ \text{days}=30\times \dfrac{1}{5}\ \text{ships}[/tex]
[tex]30\ \text{days}=6\ \text{ships}[/tex]
So, in a month 6 ships are captured.

The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 26 percent of its business on Friday night, 34 percent on Saturday night, and 24 percent on Thursday night. What seasonal relatives would describe this situation?
Answer: See Explanation
Explanation:
The work done for each day is written below:
Thursday night = 24%
Friday night = 26%
Saturday night = 34%
Wednesday night = 100% - (24% + 26% + 34%) = 100% - 84% = 16%
Let's assume that sales in a week is represented by x. Therefore average sales in week if x = 1 will be 1/4 = 0.25.
Seasonal relative will be:
= Sales in a day /Average sales in a week
Wednesday = 16% / 0.25 = 0.16 / 0.25 = 0.64
Thursday = 24% / 0.25 = 0.96
Friday = 26% / 0.25 = 1.04
Saturday = 34% / .25 = 1.36
