Consider the following two mutually exclusive projects:

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

$0$$ $30,000$$ $30,000$

$113,70015,600$

$214,20012,200$

$313,40013,300$

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?
