Your division is considering $2$ projects. It$$s WACC is $12\%,$ and the projects$$ after$-$tax cash flows

$($in millions of dollars$)$ would be as follows:

$01234$

Project A $-$$$30$ $$5$ $$10$ $$15$ $$20$

Project B $-$$$30$ $$20$ $$10$ $$8$ $$6$

a$.$ Calculate the projects$$ NPVs$,$ IRRs, and MIRRs.
