Thornley Machines is considering a 3-year project with an initial cost of $618,000. The project will not directly produce any sales but will reduce operating costs by $265,000 a year. The equipment is depreciated straight-line to a zero book value over the life of the project. At the end of the project the equipment will be sold for an estimated $60,000. The tax rate is 34%. The project will require $23,000 in extra inventory for spare parts and accessories. Should this project be implemented if Thornley's requires a 9% rate of return? Why or why not? Also calculate the IRR and the MIRR if the reinvestment rate is 6.5%? I have the NPV - $27,354 but I cannot get the IRR and MIRR
