\n" ); document.write( "6g = 12r
\n" ); document.write( "12g + 24r = 1200 cents
\n" ); document.write( "----
\n" ); document.write( "g = 2r
\n" ); document.write( "Substitute and solve for \"r\":
\n" ); document.write( "12(2r) + 24r = 1200
\n" ); document.write( "24r + 24r = 1200
\n" ); document.write( "48r = 1200
\n" ); document.write( "r = 25 cents (cost of one orange)
