Consider the following two mutually exclusive projects:

Year	Cash Flow (X)	Cash Flow (Y)
0	$23,900	$23,900
1	13,100	9,300
2	9,480	10,620
3	7,890	11,180

a.	What is the IRR of Project X? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
b.	What is the IRR of Project Y? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
c.	What is the crossover rate for these two projects? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
