Price ---------------- quantity
\n" ); document.write( "jelly beans $2.70 ---------------- x kgs
\n" ); document.write( "mints $2.10%------ 500 - x kgs
\n" ); document.write( "Mixture 2.52% ---------------- 500
\n" ); document.write( "Total 500 kgs
\n" ); document.write( "2.7 x + 2.1 ( 500 - x ) = 1260
\n" ); document.write( "2.7 x + 1050 - 2.1 x = 1260
\n" ); document.write( "2.7 x - 2.1 x = 1260 - -1050
\n" ); document.write( "0.6 x = 210
\n" ); document.write( "/ 0.6
\n" ); document.write( " x = 350 kgs $2.70 jelly beans
