Blooper Industries must replace its magnoosium purification system. Quick & Dirty Systems sells a relatively cheap purification system for $10 million. The system will last 5 years. Do-It-Right sells a sturdier but more expensive system for $12 million, it will last for 8years. Both systems entail $1 million in operating costs; both will be depreciated in an asset class that has a CCA rate of 30%; neither will have any salvage value at the end of its life. The firm's tax rate is 35%, and the discount rate is 12%. Which system should blooper install?

The answer should be in excel with details, please?
