For example, 13 million should be entered as 13,000,000. $ Now assume that Projects C and D are mutually exclusive. Project D has an NPV of $400,000, whereas Project C has an NPV of $350,000 What is the firm's optimal capital budget in this case? Write out your answer completely. For example, 13 million should be entered as 13,000,000. $ Ignore Part b and now assume that each of the projects is independent but that management decides to incorporate project risk differentials. Management judges Projects B, C, D, and E to have average risk, Project A to have high risk, and Projects F and G to have low risk. The company adds 2% to the WACC of those projects that are significantly more risky than average, and it subtracts 2% from the WACC of those projects that are substantially less risky than average. What is the firm's optimal capital budget in this case? Write out your answer completely. For example, 13 million should be entered as 13,000,000. $
