Q3) Masters Machine Shop is considering a four year project to improve its production efficiency. Buying a new machine press for $385,000 is estimated to result in $145,000 in annual pretax cost savings. The press falls in the MACRS five-year class, and it will have a salvage value at the end of the project of $45,000. The press also requires an initial investment in spare parts inventory of $20,000, along with an additional $3,100 in inventory for each succeeding year of the project. If the shop's tax rate is 22 percent and its discount rate is 9 percent, should the company buy and install the machine press? Q2) Dog Up! Franks is looking at a new sausage system with an installed cost of $460,000. This cost will be depreciated straight-line to zero over the project's five-year life, at the end of which the sausage system can be scrapped for $55,000. The sausage system will save the firm $155,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $29,000. If the tax rate is 21 percent and the discount rate is 10 percent, what is the NPV of this project
