1.25x+.75(200-x)=.95*200
\n" ); document.write( "1.25x+150-.75x=190
\n" ); document.write( ".50x=190-150
\n" ); document.write( ".50x=40
\n" ); document.write( "x=40/.50
\n" ); document.write( "x=80 pounds of $1.25 seed is used.
\n" ); document.write( "200-80=120 pounds of $.75 seed is used.
\n" ); document.write( "Proof:
\n" ); document.write( "1.25*80+.75*120=.95*200
\n" ); document.write( "100+90=190
\n" ); document.write( "190=190
\n" ); document.write( "
