4x+3.50(5-x)=18
\n" ); document.write( "4x+17.5-3.5x=18
\n" ); document.write( "4x-3.5x=18-17.5
\n" ); document.write( ".5x=.5
\n" ); document.write( "x=.5/.5
\n" ); document.write( "x=1 pound of the $4.00 candy.
\n" ); document.write( "5-1=4 pounds of the $3.50 candy.
\n" ); document.write( "Proof:
\n" ); document.write( "4*1+3.5*4=18
\n" ); document.write( "4+14=18
\n" ); document.write( "18=18
