Answer: 3.63 years.
Explanation:
The Payback period of a machine refers to how long it will take to repay it's initial investment. In this case, how long it will take to repay $54,000.
The Net Income is given in the income statement. The Depreciation needs to be added back to this income though because it is a non-cash expense so failing to add it back understates the actual amount of money that the company is getting from the machine.
Total Annual Payback = Net Income + Depreciation
= 5,850 + 9,000
= $14,850
Payback Period is,
= Initial Cost / Annual Inflow
= 54,000 / 14,850
= 3.63 years
