Answer:
3 years
Step-by-step explanation:
The computation of the payback period is shown below:
Payback period = Initial investment ÷ Net cash flow
where,
Initial investment is $15,000
And, the net cash flow would be
= Year 1 + year 2 + year 3 + year 4
= $5,000 + $5,000 + $5,000 + $5,000
= $20,000
As we see that the net cash flow is recovered in three years that means net cash flows and the initial investment are equal
So,
Payback period would be
= $15,000 ÷ $15,000
= 3 years
