Consider the following two mutually exclusive projects:

Year Cash Flow $($X$)$ Cash Flow $($Y$)$

$0$$ $16,400$$ $16,400$

$16,6607,190$

$27,2407,780$

$34,7603,530$

What is the IRR of Project X$?$

Note: Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.$

What is the IRR of Project Y$?$

Note: Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.$

What is the crossover rate for these two projects?
