Final answer:
The project achieves payback within the first three years.
Step-by-step explanation:
Project B's cash flows are as follows:
Time: 0 1 2 3 4 5
Cash Flow: -$11,000 $3,350 $4,180 $1,520 $0 $1,000
The payback period is the time it takes for an investment to recover its initial cost. To calculate the payback period, we need to determine when the cumulative cash flows become equal to or greater than zero. From the cash flows given, we can see that the cumulative cash flows become equal to or greater than zero in year 3. Therefore, the project achieves payback within the first three years.
