Please answer Problem $7$a$-$g:

NPV versus IRR. Consider the following two mutually exclusive projects:

Year Cash flow $($X$)$ Cash flow $($Y$)$

$0-9,500-9,500$

$15,8003,500$

$24,0005,000$

$34,0006,000$

$7$a$.$ The NPV for X is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $10\%.$

$7$b$.$ The NPV for Y is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $10\%.$

$7$c$.$ The NPV for X is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $15\%.$

$7$d$.$ The NPV for Y is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $15\%.$

$7$e$.$ The NPV for X is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $24\%.$

$7$f$.$ The NPV for Y is $$\_\_\_\_\_\_\_\_\_\_$if the required rate of return is $24\%.$

$7$g$.$ The cross overrate for these two projects is $\_\_\_\_\_\%.$
