1) Considering the four projects that we discussed and last session's calculations for WACC1, WACC2 and Retained earnings breakpoint, what is the firm's optimal capital budget? Project A has a cost of $750,000 and an IRR of 11.63% Project B has a cost of $1,200,000 and an IRR of 13.03% Project C has a cost of $800,000 and an IRR of 12.43% Project D has a cost of $300,000 and an IRR of 11.61% 2) Given the following information about two mutually exclusive projects, calculate each project's IRR and NPV and provide your acceptance/rejection decision (assuming a WACC of 10%).
