The Unlimited, a national retailing chain, is considering an investment in one of two mutually exclusive projects. The discount rate used for Project A is 12 percent. Further, Project A costs $15,000, and it would be depreciated using MACRS. It is expected to have an after-tax salvage value of $5,000 at the end of 6 years and to produce after-tax cash flows (including depreciation) of $4,000 for each of the 6 years. Project B costs $14,815 and would also be depreciated using MACRS. B is expected to have a zero salvage value at the end of its 6-year life and to produce after-tax cash flows (including depreciation) of $5,100 each year for 6 years. The Unlimited marginal tax rate is 40 percent. What risk-adjusted discount rate will equate the NPV of Project B to that of Project A?
