Your division is considering two projects. Its WACC is 10% (weighted average cost of capital, that represent a firms cost of capital in which each category of capital is proportionately weighted), the projects after-tax cash flows (in millions of dollars) would be as follows:

Project A

0 = - $30

1 = - $ 5

2 = $ 10

3 = $ 15

4 = 20

Project B

0 = - $ 30

1 = $ 20 2 = $10 3 = $8 4 = $6

Calculate the projects NPVs, IRRs and paybacks.
