Payback, NPV$,$ and MIRR

Your division is considering two investment projects, each of which requires an up$-$front expenditure of $$25$ million. You estimate that the cost of capital is $12\%$ and that the investments will produce the following after$-$tax cash flows $($in millions of dollars$)$:

Year Project A Project B

$1520$

$21010$

$3158$

$4206$

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

Project A:

years

Project B:

years

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:
