Hagar Industrial Systems Company (HISC) is trying to decide between two different conveyor belt systems. System A costs $295,000, has a 4-year life, and requires $97,000 in pretax annual operating costs. System B costs $375,000, has a 6-year life, and requires $91,000 in pretax annual operating costs. Both systems are to be depreciated straight-line to zero over their lives and will have zero salvage value. Whichever project is chosen, it will not be replaced when it wears out. The tax rate is 21 percent and the discount rate is 9 percent. Calculate the NPV for both conveyor belt systems. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Starset Machine Shop is considering a 4-year project to improve its production efficiency. Buying a new machine press for $420,000 is estimated to result in $166,000 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 $66,000. The press also requires an initial investment in spare parts inventory of $27,000, along with an additional $3,450 in inventory for each succeeding year of the project. The shop's tax rate is 22 percent and its discount rate is 9 percent. (MACRS schedule) Calculate the NPV of this project. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
