Answer:
a. 5.85 years
b. 17.5%
Explanation:
a. For the computation of payback period first we need to find out the annual cash flow which is shown below:-
Annual Cash Inflow = Sales - Material - Selling and Administrative Expenses - Income Tax
= $75,000 - $40,000 - $7,500 - $7,000
= $20,500
Payback period = Initial investment ÷ Annual cash flow
= $120,000 ÷ $20,500
= 5.85 years
b. The computation of the accounting rate of return is shown below:-
accounting rate of return = Net income ÷ Average investment
= $10,500 ÷ ($120,000 ÷ 2)
= $10,500 ÷ $60,000
= 17.5%
