Payback, NPV$,$ and MIRR

Your division is considering two investment projects, each of which requires an up$-$front expenditure of $$24$ million. You estimate that the cost of capital is $9\%$ and that the investments will produce the following after$-$tax cash flows $($in millions of dollars$)$:

$\backslash$table$[[$Year$,$Project A$,$Project B$],[1,5,20],[2,10,10],[3,15,8],[4,20,6]]$

a$.$ What is the regular payback period for each of the projects? Round your answers to two decimal places.

Project A: $q,$ years

Project B: $$ years

b$.$ What is the discounted payback period for each of the projects? Do not round intermediate calculations. Round your answers to two decimal places.

Project A: $q,$ years

Project B: $$ years

c$.$ If the two projects are indefendent and the cost of capital is $9\%,$ which project or projects should the firm undertake?

The firm should undertake $$

d$.$ If the two projects are mutually exclusive and the cost of capital is $5\%,$ which project should the firm undertake?

The firm should undertake $$

e$.$ If the two projects are mutually exclusive and the cost of capital is $15\%,$ which project should the firm undertake?

The firm should undertake $$

f$.$ What is the crossover rate? Round your answer to two decimal places.

$\%$

g$.$ If the cost of capital is $9\%,$ what is the modified IRR $($MIRR$)$ of each project? Do not round intermediate calculations. Round your answers to two decimal places.

Project A: $\%$

Project B: $\%$
