I need "E-H" can't find answers or examples

a. Calculate the payback period for projects Alpha, Beta, and Delt b. Calculate the NPV for each project using a cost of capital of from 0-20\%, in 2% intervals. c. Draw the NPV profiles for each project (on the same graph). d. Calculate the IRR for each project. e. Calculate the Profitability Index (PI) for each project. f. Assume that these projects are independent projects. Evaluate the acceptability of each project using the payback period, NPV, PI, and IRR methods. g. Now assume that these projects are mutually exclusive. Rank the projects according to the payback period, NPV, and IRR methods. h. Do the rankings conflict? If so, which project would you recommend, and why? a. Calculate the payback period for projects Alpha, Beta, and Delt b.
