Answer:
22.5%
Step-by-step explanation:
For computation of return on investment first we need to find out the average investment and average income per year which is shown below:-
Average investment = Proposed investment ÷ Average
= $800,000 ÷ 2
= $400,000
Now, the Average income per year = Expected total net income ÷ Number of year
= $360,000 ÷ 4
= $90,000
Return on investment = Average income per year ÷ Average investment
= $90,000 ÷ $400,000
= 0.225
or
= 22.5%
