Answer:
The simple rate of return= 58.65%
Explanation:
Annual Return from the old machine = 22,500/9=2,500
Annual profit = savings less depreciation=139,500-89,500=50,000
Total annual return = 2500 + 50,000 = 52,500
Average investment = $(805,500+ 0)/9 = 89,500
Simple average return = average annul return/ Average investment
Average investment = (Initial cost + salvage value)/2
Simple average return = (52,500/ 89,500) × 100 = 53.159
The simple rate of return= 58.65%
