Blooper Industries must replace its magnoosium purification system. Quick & Dirty Systems sells a relatively cheap purification system

for $$8$ million. The system will last $4$ years. Do$-$It$-$Right sells a sturdier but more expensive system for $$18$ million; it will last for $9$ 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 $30\%,$ and the discount rate is $16\%.$
