family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas. During one particular week, the two cars went a combined total of 2050 miles, for a total gas consumption of 70 gallons. How many gallons were consumed by each of the two cars that week? Note that the ALEKS graphing calculator can be used to make computations easier. First car: ___ gallons second car: ____ gallons
