I need help with the last part. Thank you!

Consider the following two mutually exclusive projects: Calculate the IRR for each project. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) What is the crossover rate for these two projects? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) What is the NPV of Projects X and Y at discount rates of 0 percent, 15 percent, and 25 percent? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
