A firm is considering replacing a machine. If kept, it will cost $15,000 to over-haul it; then, annual O&M costs will be $12,500 annually. At the end of a 5-year planning horizon, the over-hauled machine will have a negligible salvage value. If replaced, a new machine will cost $50,000; its uniform annual O&M costs will be $2,500; at the end of the 5-year planning horizon, the new machine will have a $10,000 salvage value. If the old machine is replaced, it will have a $2,500 trade-in value. Using an insider viewpoint, a PW analysis, and a MARR of 10%, what are the PW values for each alternative?
