Answer:
a. 2 years.
Step-by-step explanation:
Annual cash flow = After-tax net income + Depreciation
Annual cash flow = $80,000 + $160,000
Annual cash flow = $240,000
Payback Period = Cost of Project / Annual cash Flow
Payback Period = $480,000 / $240,000
Payback Period = 2 years
So, the payback period for the new equipment is 2 years.
