You are the project manager assigned to a project early in the project lifecycle. One of the things that must be done is to do a justification for the project. Since very little information is known about the project, the estimates are considered to be rough estimates. The following table is the project managers estimate of the cash flow that will take place over the next five years.

End of Year	Cash Flow In	Cash Flow Out
1	0	15,000
2	15,000	20,000
3	20,000	15,000
4	30,000	10,000
5	45,000	5,000

1. What is the payback period for this project?
2. What is the net cash flow at the end of five years?
