Time Cash Flow -5,000 3,000 2,000 1,000 3,000 1. WITHOUT USING EXCEL a. Compute the payback and the discounted payback using a 10 percent discount rate and tell me what the decision rule is for payback and discounted payback b. Compute the NPV (using a 20-discount rate) and the IRR, and then tell me what the decision rule is for NPV and IRR c. Compute the modified IRR with a 10 percent reinvestment rate and tell me what the decision rule is for modified IRR d. compute the equivalent annual annuity with a 10 percent reinvestment rate, and then tell me what the decision rule is if you compare these cash flows to another project.
