Answer:
a) 17.5%
Explanation:
The computation of the simple rate of return on the investment is shown below:
Simple rate of return = Annual net income ÷ Initial investment
where,
Annual net income is
= Sales revenue - cash operating expenses - depreciation expenses
= $250,000 - $100,000 - ($400,000 ÷ 5)
= $70,000
And, the initial investment is $400,000
So, the simple rate of return is
= $70,000 ÷ $400,000
= 17.5%
Dividing the annual net income by the initial investment we can get the simple rate of return
