You are analyzing two proposed capital investments with the following cash flows:

Year		Project X		Project Y
0		- $20,000		- $20,000
1		12,630		6,770
2		5,760		6,770
3		6,160		6,770
4		2,120		6,770

The cost of capital for both projects is 10 percent. Calculate the profitability index (PI) for each project. (Do not round discount factors. Round intermediate calculations to 2 decimal places, e.g. 15.25 and final answer to 4 decimal places, e.g. 1.2527.)

1.PI for project x?

2. PI for project y?

3.Which project, or projects, should be accepted if you have unlimited funds to invest?

4.Which project should be accepted if they are mutually exclusive?
