4.50x+2.50(100-x)=3.23*100
\n" ); document.write( "4.50x+250-2.5x=323
\n" ); document.write( "2x=323-250
\n" ); document.write( "2x=73
\n" ); document.write( "x=73/2
\n" ); document.write( "x=36.5 pounds of $4.50 almonds are used.
\n" ); document.write( "100-36.5=63.5 pounds of $2.50 walnuts are used.
\n" ); document.write( "Proof:
\n" ); document.write( "4.5*36.5+2.5*63.5=323
\n" ); document.write( "164.25+158.75=323
\n" ); document.write( "323=323
\n" ); document.write( "
