A company has a $12\%$ WACC and is considering two mutually exclusive investments $($that cannot be repeated$)$ with the following cash flows:

a$.$ What is each project's NPV$?$ Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest cent.

Project A: $

Project B: $

b$.$ What is each project's IRR? Do not round intermediate calculations. Round your answers to two decimal places.

c$.$ What is each project's MIRR? $($Hint: Consider Period $7$ as the end of Project B$\text{'}$s life.$)$ Do not round intermediate calculations. Round your answers to two decimal places.

d$.$ From your answers to parts a$-$c$,$ which project would be selected?

If the WACC was $18\%,$ which project would be selected?

f$.$ Calculate the crossover rate where the two projects' NPVs are equal. Do not round intermediate calculations. Round your answer to two decimal places.

$\%$

g$.$ What is each project's MIRR at a WACC of $18\%?$ Do not round intermediate calculations. Round your answers to two decimal places.
