NEW PROJECT ANALYSIS Holmes Manufacturing is considering a new machine that costs $250,000 and would reduce pretax manufacturing costs by $90,000 annually. Holmes would use the 3-year MACRS method to depreciate the machine, and management thinks the machine would have a value of $25,000 at the end of its 5-year operating life. The applicable depreciation rates are 33%, 45%, 15%, and 7%. Net operating working capital would increase by $25,000 initially, but it would be recovered at the end of the project's 5-year life. Holmes's marginal tax rate is 4096, and a 13% WACC is appropriate for the project. a. Calculate the project's NPV. Round your answer to the nearest cent. Calculate the project's IRR. Round your answer to two decimal places. Calculate the project's MIRR. Round your answer to two decimal places Calculate the project's payback. Round your answer to two decimal places years b. Assume management is unsure about the $90,000 cost savings-this figure could deviate by as much as plus or minus 20%. what would the NPV be under each of these situations? Round your answers to the nearest cent. Negative amount should be indicated by a minus sign 20% savings increase, $ 20% savings decrease
