Answer:
13.2%
Explanation:
The formula to compute the average rate of return is shown below:
= Average net income ÷ average investment
where,
Average net income is
= $231,000 ÷ 5 years
= $46,200
And, the average investment would be
= (Initial investment + salvage value) ÷ 2
= ($700,000 + $0) ÷ 2
= $700,000 ÷ 2
= $350,000
Now put these values to the above formula
So, the rate would equal to
= $46,200 ÷ $350,000
= 13.2%
