12.Calculating EACYou are evaluating two different silicon wafer milling machines. The Techron I costs $265,000, has a 3-year life, and has pretax operating costs of $41,000 per year. The Techron II costs $330,000, has a 5-year life, and has pretax operating costs 196 of $52,000 per year. For both milling machines, use straight-line depreciation to zero over the projects life and assume a salvage value of $25,000. If your tax rate is 21 percent and your discount rate is 9 percent, compute the EAC for both machines. Which do you prefer? Why?

13.Cost-Cutting ProposalsStarset Machine Shop is considering a 4-year project to improve its production efficiency. Buying a new machine press for $670,000 is estimated to result in $245,000 in annual pretax cost savings. The press falls in the 5-year MACRS class, and it will have a salvage value at the end of the project of $55,000. The press also requires an initial investment in spare parts inventory of $20,000, along with an additional $2,500 in inventory for each succeeding year of the project. If the shops tax rate is 23 percent and the discount rate is 8 percent, should the company buy and install the machine press?
