You are taking a trip on the highway in a car that gets a gas mileage of about 26 miles per gallon for highway driving. You start with a full tank of 12 gallons of gasoline. Use Exercise 47 to write an equation relating the number of gallons of gas in your tank g and the number of miles m that you have driven on your trip.
Under selected conditions, a sedan gets 22 mpg in city driving and 32 mpg for highway driving. The model $G=\frac{1}{22} c+\frac{1}{32} h$ represents the amount of gasoline used (in gal) for $c$ miles driven in the city and $h$ miles driven on the highway. Determine the amount of gas required to drive $220 \mathrm{mi}$ in the city and $512 \mathrm{mi}$ on the highway.
