.12X+.06(240-X)=.11*240
\n" ); document.write( ".12X+14.4-.06X=26.4
\n" ); document.write( ".06X=26.4-14.4
\n" ); document.write( ".06X=12
\n" ); document.write( "X=12/.06
\n" ); document.write( "X=200 PDS. OF SOYBEANS IS USED.
\n" ); document.write( "240-200=40 LBS. OF CORNMEAL IS USED.
\n" ); document.write( "PROOF:
\n" ); document.write( ".12*200+.06*40=.11*240
