Answer:
2 years
Step-by-step explanation:
Payback period is the amount of time it takes to recover the amount invested in a project from its cumulative cash flows
In the first year, -$85,000 + $30,000 = -$55,000 is recovered
In the second year, -$55,000 + $55,000 = 0
The total amount invested is recovered in the second year
