1. A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas tank, the driver got on a highway and drove for a while. A.) how many gallons are left in the tank when the car has traveled the following distance on the highway?

1.) 90 miles
2.) 246 miles

B.) Write an equation that makes it easier to find the amount of gas left in the tank, x, if we know the car had traveled d miles
