Which Car Can You Buy?
Pretend you are 16, just got your driver’s license, have a job after school, and are ready to buy a car. You can spend $350 per month on the car payment and gas. You have narrowed your choices down to either a Volkswagen Jetta or a Toyota Corolla (or 2 other cars). The Corolla costs a little more but gets better gas mileage so it will cost a little less to drive per month. Before your parents let you buy a car, they want you to figure out how many miles you can drive per month for each car without going over your $350 limit.
Gather information about two cars (price of buying the car, miles per gallon, and average price for a gallon of gas). Build a system of linear
equations for the price of
both cars. decide which car you can drive the most without going over $350.
