Dublin Methodist Hospital is considering the purchase of a new rapid diagnostic machine. The system will cost $400,000 and will be depreciated straight-line to zero over its five-year life. It will be worth $50,000 at the end of that time. The hospital will save $130,000 per year in laboratory costs and will also be able to reduce their inventory of lab supplies by $50,000 upon purchasing the new machine. If the tax rate is 35%, what is the IRR for this project? he answer should be 17.25%. Please walk me through how you got it.
