Answer:
Simple rate of return = 6.25%
Explanation:
As per the data given in the question,
Net operating income = saving - depreciation on machine
Investment = cost price - scrap value
So, we can calculate the simple rate of return by using following formula:
Simple rate of return = Net operating income ÷ investment
By putting the value, we get
= ($138,000 - $89,200) ÷ ($802,800 - $22,200)
= 0.0625
= 6.25%
