Answer:
13.9%
Step-by-step explanation:
Given that:
Cost of the machine: $2,000
Net income increasing: $300
Number of years: 15 => depreciation per year: $2,000 /15 =$133
=> Average Return: $300 - $133 = $167
As we know:
Average investment (Assuming no salvage value:)
= (beginning investment + ending investing)/2
(2000 + 0 )/ 2 = 1,200
So, the unadjusted rate of return based on the average cost of the investment:
=
= $167 / $1,200
= 0.139
= 13.9%
