Your division is considering two projects. Its WACC is 7.5%, and the projects' after-tax cash flows (in millions of dollars) would be as follows: Calculate the projects' NPVs and IRRS i = 7.5% ||NPVA = NPV = We find the internal rate of return with Excel's IRR function: IRRA = IRR = Time 0 1 2 3 4 Expected Cash Flows Project A ($50) $5 $5 $20 $20 Use Excel's NPV function. Note that the range does not include the initial costs, which are added separately. Project B ($100) $20 $25 $28 $30
