Bruno's is analyzing two machines to determine which one it should purchase. The company requires a rate of return of 14 percent and uses straight-line depreciation to a zero book value. Machine A has a cost of $290,000, annual operating costs of $8,000, and a 3-year life. Machine B costs $180,000, has annual operating costs of $12,000, and has a 2-year life. Whichever machine is purchased will be replaced at the end of its useful life. Which machine should Bruno's purchase and why?
