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

Year		Project X		Project Y
0		- $20,000		- $20,000
1		13,630		7,070
2		5,660		7,070
3		5,760		7,070
4		1,820		7,070

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.)
