Answer:
The average rate of return for this investment is 21%
Explanation:
Average rate of return : The average rate of return shows the ratio between average net income and average initial investment.
Mathematically,
Average rate of return = Average Net income ÷ Average Initial Investment
where Average Net income = Total years of net income ÷ Number of years
= ($100,000 + $60,000 + $30,000 + $10,000 + $10,000) ÷ 5
= $42,000
And, Average Initial Investment = Initial Investment ÷ 2
= $400,000 ÷ 2
= $200,000
Now, average rate of return = $42,000 ÷ $200,000
= 21%
Thus, the average rate of return for this investment is 21%
