MF enterprise is considering two mutually exclusive projects. Both projects require an initial investment of $10,000 and are typical average-risk projects for the firm. Project A has an expected life of 2 years with after-tax cash inflows of $6,000 and $8,000 at the end of Years 1 and 2, respectively. Project B has an expected life of 4 years with after-tax cash inflows of $4,000 at the end of each of the next 4 years. The firm's WACC is 10%. i.
