Answer:
7.47 years
Step-by-step explanation:
Payback period calculates the amount of the time it takes to recover the amount invested in a project from its cumulative cash flows.
= amount invested / cash flows
To derive cash flow: (S - C - D) x (1 - t) + D
S = sales = $16,100
C = Cost of goods sold = $7,900
D = deprecation = $4,100
T = tax = 40%
$16,100 - $7,900 - $4,100 = $4100
$4100 × 0.6 = $2460
$2460 + $4,100 = $6560
$49,000 / $6560 = 7.47 years
