Precision Tool is analyzing two machines to determine which one it should purchase. The company requires a 15 percent rate of return and uses straight-line depreciation to a zero book value over the life of its equipment. Machine A has a cost $892,000, annual operating costs of $26,300, and a 4 year life. Machine B costs $1,127,000, has annual operating costs of $19,500, and has a 5 year life. Whichever machine is purchased will be replaced at the end of its useful life. Which machine should Precision Tool purchase? Can you give the method too please
