Answer:
Payback =7.1 years
Explanation:
If a project has equal annual cash-flows, the payback period can be calculated using the formula:
[tex]Payback=\frac{CostOfMachine}{AnnualCashflows}[/tex]
In calculating the annual cash-flows, depreciation is not included as it is a non-cash item. As such, the $46,860 annual depreciation figure should not affect the payback period calculation, but instead, the $66,000 annual cash-flows will be used.
As such:
[tex]Payback=\frac{468600}{66000}=7.1 years[/tex]
