Blooper Industries must replace its magnoosium purification system. Quick & Dirty Systems sells a relatively cheap purification system for $15 million. The system will last 5 years. Do-It-Right sells a sturdier but more expensive system for $20 million; it will last for 10 years. Both systems entail $1 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 firms tax rate is 30%, and the discount rate is 13%. Either machine will be replaced at the end of its life.
