Answer:
23%
Step-by-step explanation:
The computation of the average rate is shown below:
But before that following calculations to be done
Annual Depreciation is
= ($132,000 - $16,000) ÷ 10
= $11,600
The Annual Net Income would increase by
= $34,000 - $5,380 - $11,600
= $17,020
Now Average Investment is
= ($132,000 + $16,000) ÷ 2
= $74000
The Average rate of return is
= Increase in Annual Net Income ÷ Average Investment
= $17,020 ÷ $74,000
= 23%
