Blooper Industries must replace its magnoosium purification system.

Quick & Dirty Systems sells a relatively cheap purification system for

$$20$ million. The system will last $4$ years. Do$-$lt$-$Right sells a sturdier but

more expensive system for $$21$ million; it will last for $6$ years. Both

systems entail $$2$ 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 $30\%,$

and the discount rate is $13\%.$
