You can solve this in a couple of ways:
\n" ); document.write( "1) Use proportions:
\n" ); document.write( "Let x = the number of gallons required to drive 518 miles. Then you can write:
\n" ); document.write( " $\"370%2F10+=+518%2Fx\"$
\n" ); document.write( " $\"x+=+5180%2F370\"$
\n" ); document.write( " $\"x+=+14\"$ gallons.\r
\n" ); document.write( "\n" ); document.write( "2) If 10 gallons are required to drive 370 miles, then the gas consumption is $\"370%2F10+=+37\"$ mpg
\n" ); document.write( "To drive 518 miles you would need $\"518%2F37+=+14\"$ gallons. \n" ); document.write( "

\n" );
