Final answer:
The payback period of the project is between Time 3 and Time 4, with the exact payback year being Time 4.38.
Step-by-step explanation:
The payback period is a method used to evaluate the time it will take for savings from an investment to equal the initial cost of the investment. To calculate the payback period for the given project, we need to sum up the cash flows until the payback is achieved. In this case, the payback period would be:
Time 0: $237,000
Time 1: $237,000 - $66,000 = $171,000
Time 2: $171,000 - $84,200 = $86,800
Time 3: $86,800 - $141,200 = -$54,400
Time 4: -$54,400 - $122,200 = -$176,600
The payback year would be between Time 3 and Time 4, since the cumulative cash flow becomes negative in Time 4. To find the exact payback year, we can calculate the fraction of the last cash flow that is needed to reach the payback point:
Payback year: Time 3 + ($122,200 / ($122,200 - (-$54,400)) * 1) = Time 3 + 1.38 = Time 4.38
