Answer:
C) 4.2 years
Step-by-step explanation:
The computation of the payback period is as follows;
As we know that
Payback Period = Initial cost ÷ Annual net cash flow
Here
Initial cost = $278000
Annual net cash flow = Incremental after tax + Depreciation per year
where,
Depreciation per year = (Original cost - Salvage value) ÷ Estimated Life
= ($278,000 - $30,000) ÷ 8 years
= $31,000
Annual net cash flow is
= $35000 + $31000
= $66000
So,
Payback Period is
= $278000 ÷ $66000
= 4.2 Years
