A family has two cars. During one particular week, the first car consumed 20 gallons of gas and the second consumed 25 gallons of gas. The two cars drove a combined total of 1425 miles, and the sum of their fuel efficiencies was 65 miles per gallon. What were the fuel efficiencies of each of the cars that week? Note that the ALEKS graphing calculator can be used to make computations easier. First car: miles per gallon X ? Second car: miles per gallon
