Answer: 27%
Explanation:
The Average rate of return is calculated by;
= Estimated Average Annual income / Average Investment
Estimated Average annual income = Total income/ years income is accrued
= 402,300/5
= $80,460
Average Investment = (Initial cost + Residual value) / 2
= (524,500 + 71,500) / 2
= $298,000
Average rate of return = 80,460/298,000
= 0.27
= 27%
