Blooper Industries must replace its magnoosium purification system. Quick & Dirty Systems sells a relatively cheap purification system for $25 million. The system will last 5 years. Do-It-Right sells a sturdier but more expensive system for $28 million; it will last for 7 years. Both systems entail $3 million in operating costs; both will be depreciated straight-line to a final value of zero over their useful lives; neither will have any salvage value at the end of its life. The firm's tax rate is 40%, and the discount rate is 16%. Either machine will be replaced at the end of its life.
