Calculate the IRR(s) and the NPV for project C. Which project(s) would you implement if the four projects were independent from cach other? d. c. Which project(s) would you implement if the four projects were mutually exclusive? Problem 2 You are thinking about getting a new grill for your backyard entertaining.
