.12x+.06(240-x)=.09*240
\n" ); document.write( ".12x+14.4-.06x=21.6
\n" ); document.write( ".06x==21.6-14.4
\n" ); document.write( ".06x=7.2
\n" ); document.write( "x=7.2/.06
\n" ); document.write( "x=120 pounds of 12%soybeans is used.
\n" ); document.write( "240-120=120 pounds of 6% cornmeal is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".12*120+.06*120=.09*240
\n" ); document.write( "14.4+7.2=21.6
\n" ); document.write( "21.6=21.6
