\n" ); document.write( "\n" ); document.write( "1st) Set up a proportion. Make sure that both ratios/fractions have the same things on top and bottom. If you put money on the top of one, the other has to have money on the top as well.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x= Cost of 35 gallons of gasoline\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "$43.12/14 gallons = x/35 gallons\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "2nd.) Cross Multiply and solve for \"x\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "$43.12/14 gallons = x/35 gallons
\n" ); document.write( "14x=$43.12(35)
\n" ); document.write( "14x=$1509.20
\n" ); document.write( "14x/14=$1509.20/14
\n" ); document.write( "x=$107.80\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "3rd.) Answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "35 gallons of gasoline will cost $107.80
\n" ); document.write( "
\n" );
