Answer:
3.1 years
Explanation:
The computation of the payback period is shown below:
Years Incremental Net Cash Flows Accumulated cash flows
0 -$370,000 -$370,000
1 $128,000 -$242,000
2 $105,000 -$137,000
3 $126,000 -$11,000
4 $123,000 $112,000
Now the Payback period is
= 3 + ($11000 ÷ $123,000)
= 3.1 years
