Q4. Nguyen 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 shop's tax rate is 23 percent and the discount rate is 8 percent, should the company buy and install the machine press
