a. What are the projects' NPVs assuming the WACC is 5\%? Round your answer to two decimal places. Do not round your intermediate calculations. Enter your answer in millions. For example, an answer of $10,550,000 should be entered as 10.55. Negative value should be indicated by a minus sign. Project A $ million Project B \$ million What are the projects' NPVs assuming the WACC is 10% ? Round your answer to two decimal places. Do not round your intermediate calculations. Enter your answer in millions. For example, an answer of $10,550,000 should be entered as 10.55. Negative value should be indicated by a minus sign. b. What are the projects' IRRs assuming the WACC is 5\%? Round your answer to two decimal places. Do not round your intermediate calculations. Project A \% Project B % What are the projects' IRRs assuming the WACC is 10% ? Round your answer to two decimal places. Do not round your intermediate calculations. Project A % Project B % What are the projects' IRRs assuming the WACC is 15% ? Round your answer to two decimal places. Do not round your intermediate calculations. Project A% Project B % . If the WACC was 5% and A and B were mutually exclusive, which project would you choose? (Hint: The crossover rate is 10.72%.) If the WACC was 10% and A and B were mutually exclusive, which project would you choose? (Hint: The crossover rate is 10.72%.) If the WACC was 15% and A and B were mutually exclusive, which project would you choose? (Hint: The crossover rate is 10.72%.)
