The HalloweenIsPasse Company has the opportunity to invest in one of two mutually exclusive machines that will produce a product it will need for the next 8 years. Machine A costs $10 million but would provide cash inflows of $4 million per year for 4 years. If Machine A were replaced, its cost would be $12 million due to inflation, and its cash inflows would increase to $4.2 million due to production efficiencies. Machine B costs $15 million and would provide cash inflows of $3.5 million per year for 8 years. If the market rate is 10 percent, which machine should be acquired?
