Can someone help me with the formula in order to figure out the breakeven points for the Oil Changes and the Brake Repairs please.

PDQ Repairs has 200 auto-maintenance service outlets nationwide. It performs primarily two lines of service: oil changes and brake repair. Oil changerelated services represent 70 % of its sales and provide a contribution margin ratio of 20 %. Brake repair represents 30 % of its sales and provides a 30 % contribution margin ratio. The companys fixed costs are $ 15,650,000 (that is, $ 78,250 per service outlet).

Calculate the dollar amount of each type of service that the company must provide in order to break even.
