Please help answer PART A ***** Thank you!

Holmes Manufacturing is considering a new machine that costs $275,000 and would reduce pretax manufacturing costs by $90,000 annually. The new machine will be fully depreciated at the time of purchase. Management thinks the machine would have a value of $22,000 at the end of its 5-year operating life. Net operating working capital would increase by $26,000 initially, but it would be recovered at the end of the project's 5-year life. Holmes's marginal tax rate is 25%, and a 12% WACC is appropriate for the project. a. Calculate the project's NPV. Negative value, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to the nearest cent. Calculate the project's IRR. Do not round intermediate calculations. Round your answer to two decimal places. Calculate the project's MIRR. Do not round intermediate calculations. Round your answer to two decimal places. Calculate the project's payback. Do not round intermediate calculations. 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? Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest cent. 20% savings increase: $ 20% savings decrease: $
