Answer:
5 years
Explanation:
The Payback period calculates the amount of the time it takes to recover the amount invested in a project to be recovered from the cumulative cash flow.
The total amount invested in the project = $-490,000
I'm the first year, the amount that would be recovered would be $-490,000 + $110,000 = $-380,000
The amount recovered in the second year is $-380,000 + 100,000 = $-280,000
The amount recovered in the 3rd year is $-280,000 + 100,000 = $-180,000
The amount recovered in the 4th year is $-180,000 + 90,000 = $-90,000
The amount recovered in the 5th year is $-90,000 + $90,000 = 0
The total amount is recovered In the 5th year.
