Answer: 4.7%
Explanation:
Expected return is calculated as:
= Risk free return + Beta ( Market risk premium)
10.8% = 5% + (1.22 × Market risk premium)
10.8% - 5% = 1.22market risk premium
5.8%/1.22 = market risk premium
Market risk premium = 0.058/1.22
Market risk premium = 0.047
Market risk premium = 4.7%

Explanation:
The marginal cost measures the change in total cost of adding on more worker divided by the change in product for this additional worker (marginal product of labor). When adding one more worker, costs will increase by $80 (wage rate), while product will increase by 75. Therefore, the marginal cost is:

The marginal cost is $1.07.
Answer:
annual sum must he set aside $16209.42
Explanation:
given data
engineer wishes = $3 million
retires time = 35 years
nominal interest = 8%
solution
we get here effective annual rate that is
interest rate =
...........1
interest rate =
interest rate = 0.08328 = 8.33%
and
now we get annual sum must he set aside that is
amount = $3 million ×
amount = $3000000 ×
amount = $16209.42
Answer:
1. 45.5%
2. 13.3%
3. 7.2%
Explanation:
The formulas and calculations are shown below:
1. Gross margin = (Sales - cost of sales) ÷ (sales) × 100
= ($10.1 million - $5.5 million) ÷ ($10.1 million) × 100
= ($4.6 million) ÷ ($10.1 million) × 100
= 45.5%
Gross profit = Sales - cost of sales
2. Operating margin = (Gross profit - selling, general and administrative expenses - research and development - annual depreciation charges) ÷ (sales) × 100
= ($4.6 million - $460,000 or $0.46 million - $1.4 million - $1.4 million) ÷ ($10.1 million) × 100
= ($1.34 million) ÷ ($10.1 million) × 100
= 13.3%
Operating income = Gross profit - selling, general and administrative expenses - research and development - annual depreciation charges
3. Net profit margin = (Operating income - taxes) ÷ (sales) × 100
= ($1.34 million - $0.6097 million) ÷ ($10.1 million) × 100
= ($0.7303 million) ÷ ($10.1 million) × 100
= 7.2%
The income tax expense = Operating income × income tax rate
= $1.34 million × 45.5%
= $0.6097 million
