O SYSTEMS OF LINEAR EQUATIONS Paul Solving a value mixture problem using a system of linear equ Español A family has two cars. The first car has a fuel efficiency of 20 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 900 miles, for a total gas consumption of 55 gallons. How many gallons were consumed by each of the two cars that week? Note that the ALEKS araphing calculator can be used to make computations easier. First car gallons Second car: gallons EE Aa
