A car traveled 278 miles on a trip. During 54 miles of the trip, the car traveled through the city and had gas mileage that was 5 fewer miles per gallon that the gas on the highway.
\n" ); document.write( "If the total amount of gasoline used for the trip was 9 gallons, find the gas mileage of the car on the highway.

\n" ); document.write( "You are close to the right equation:
\n" ); document.write( ":
\n" ); document.write( "gallons used = \"dist%2Fmpg\"
\n" ); document.write( ":
\n" ); document.write( "City gal + highway gal = 9 gal
\n" ); document.write( "\"54%2F%28%28x-5%29%29\" + \"224%2Fx\" = 9 is the equation you want
\n" ); document.write( "
\n" );
