Answer:
3 years
Explanation:
Since the income tax is ignored, so the operating cash flows would be
= EBIT + Depreciation - Income tax expense
= $105,000 + $45,000 - $0
= $150,000
The operating cash flows are same for ten years
And, the initial investment is $450,000
So, the payback period would be
= Initial investment ÷ Net cash flows
= $450,000 ÷ $150,000
= 3 years
