Management is considering updating its computer with a faster model that would eliminate all of the overtime processing. ??Current Machine??New Machine???Original purchase cost??$15,000???$25,000????Accumulated depreciation??$  6,000???_????Estimated annual operating costs??$25,000???$20,000????Useful life??5 years???5 years????
