you are evaluating two different machine. The JJ1 costs $290,000, has three year life and has pretax operating costs of $67,000 per year. The JJ2 costs $510,000, has five year life and has pretax operating costs of $35000 per year. for both Machine use straight line depreciation to zero over the projects life and assume a salvage value of $40,000. if your tax rate is 35 percent and your discount rate is 10 percent , compute the EAC fo both machines.
