Final answer:
The payback period for the Ramson Corporation machine is approximately 6.80 years, and the simple rate of return is approximately 5.48%.
Step-by-step explanation:
To calculate the payback period for the Ramson Corporation machine, divide the initial cost of the machine by the annual cash savings. The payback period is calculated as follows:
Initial cost of machine: $633,080
Annual cash operating cost savings: $93,100
Payback period = Initial cost / Annual savings
Payback period = $633,080 / $93,100
Payback period ≈ 6.80 years (rounded to two decimal places)
To calculate the simple rate of return, we need to use the average annual profit from the investment and the initial cost of the machine. Average annual profit is the difference between the annual cash operating cost savings and the depreciation. The simple rate of return is computed as follows:
Annual cash operating cost savings: $93,100
Salvage value at the end of 9 years: $107,220
Annual depreciation = (Initial cost - Salvage value) / Useful life
Average annual profit = Annual cash operating cost savings - Annual depreciation
Annual depreciation = ($633,080 - $107,220) / 9 years
Annual depreciation = $525,860 / 9
Annual depreciation ≈ $58,428
Average annual profit = $93,100 - $58,428
Average annual profit ≈ $34,672
Simple rate of return = (Average annual profit / Initial cost) * 100
Simple rate of return ≈ ($34,672 / $633,080) * 100
Simple rate of return ≈ 5.48% (rounded to two decimal places)
