CSM Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $490,000 is estimated to result in $189,000 in annual pretax cost savings. The press falls in the MACRS five-year class (MACRS Table), and it will have a salvage value at the end of the project of $57,500. The press also requires an initial investment in spare parts inventory of $21,500, along with an additional $3,500 in inventory for each succeeding year of the project. The shops tax rate is 35 percent and its discount rate is 11 percent.

Calculate the NPV. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

I asked this question earlier today and was given the answer of $87,987.29 but it is not the correct answer, i am thinking it might be because of the rounding. it should not be rounded until the end
