Answer:
4 years
Explanation:
The computation of the payback period is shown below:
Payback period is
= Cost of a Machine ÷ Annual cash flow
where,
Cost of a machine = $24,000
And, the annual cash flow is
= Net Income + Depreciation expense
= $2,000 + $4,000
= $6,000
Now placing these values to the above formula
So, the payback period is
= $24,000 ÷ $6,000
= 4 years
