A company's CEO launched a feasibility study by asking, why pay someone to dig coal of out of the ground and then pay someone else to put our waste into a landfill? Why not just burn our own waste? The company is proposing to build a $10-million power plant to burn its waste as fuel, thereby saving $2.8 million a year in coal purchase. Company engineers have determined that the waste-burning power plant will be environmentally sound, and after its four-year study period, the plant can be sold to a local electric utility for $5 million. O What is the IRR of this proposed power plant? 2 If the firm's MARR is 15% per year, should this project be undertaken?
