I have 200 maintenance service outlets, we provide two lines of service: oil chnage, and brake repair. Our oil change related services present 70% of its sale and provide a contribution margin ratio of 20%. Brake repair represent 30% of its sales and provides 60% contribution margin ratio. Our company fixed costs are $16,000,000 (that $80,000 per service outlet).
Calculate the dollar amount of each type of service that we must provide to break even?
