Answer:
The simple rate of return= 53.2%
Step-by-step explanation:
Annual Return from the old machine 132,500 - 88,100= 44,400
Annual return from the sale of the old machine =21,100/9=2433.333333
Total annual return - 2433.33 + 44,400 =46833.33
Average investment = $(792,900 + 0)/9 = 88100
Simple average return = average annul return/ Average investment
Average investment = (Initial cost + salvage value)/2
Simple average return = (46,833.33/ 88,100) × 100 = 53.159
The simple rate of return= 53.2%
