9.20X+8.50(5.5-X)=48.50
\n" ); document.write( "9.20X+46.75-8.50X=48.50
\n" ); document.write( ".70X=48.50-46.75
\n" ); document.write( ".70X=1.75
\n" ); document.write( "X=1.75/.70
\n" ); document.write( "X=2.5 LBS. OF $9.20 COFFEE.
\n" ); document.write( "5.5-.5=3 LBS OF $8.50 COFFEE.
\n" ); document.write( "PROOF:
\n" ); document.write( "9.20*2.5+8.50*3=48.50
\n" ); document.write( "23+25.5=48.50
\n" ); document.write( "48.50=48.50\r
