Answer:
15%
Step-by-step explanation:
The formula to compute the accounting rate of return is shown below:
= Annual net income ÷ average investment
where,
Annual net income would be
= Annual revenues - annual expenses
= $68,950 - $40,000
= $28,950
And, the average investment would be
= (Initial investment + salvage value) ÷ 2
= ($310,000 + $76,000) ÷ 2
= $386,000 ÷ 2
= $193,000
Now put these values to the above formula
So, the rate would equal to
= $28,950 ÷ $193,000
= 15%
