3C+G=175 OR G=175-3C
\n" ); document.write( "2C+4G=200 NOW SUBSTITUTE (175-3C) FOR G IN THIS EQUATION & SOLVE FOR C
\n" ); document.write( "2C+4(175-3C)=200
\n" ); document.write( "2C+700-12C=200
\n" ); document.write( "-10C=200-500
\n" ); document.write( "-10C=-500
\n" ); document.write( "C=-500/-10
\n" ); document.write( "C=50 COST OF THE CHOCOLATE BAR.
