BC Minerals is considering a new production process. Two alternative pieces of equipment are available. Alternative P costs $100,000, has a 10-year life, and is expected to generate annual cash inflows of $22,000 in each of the 10 years. Alternative R costs $85,000, has an 8-year life, and is expected to generate annual cash inflows of $18,000 in each of the eight years. BC Minerals's weighted cost of capital is 12 percent. Using the equivalent annual annuity method, which alternative should be chosen?
