You have identified two mutually exclusive projects that have the following cash flows:
Year	Project A	Project B
0	-45,000	-42,000
1	25,000	7,800
2	21,500	14,500
3	11,000	21,000
4	8,900	27,000
a.	Assuming that required rate is 12% what is the Net Present Value of each of these projects?
b.	What is the Internal Rate of Return of each of these projects?
c.	Assuming cash flows can be reinvested at 15% rate, what is the Internal Rate of Return for each of these projects?
d.	What is the crossover rate? Use discounting approach to modify cash flow if needed.
