.12x+.06(240-x)=.08*240
\n" ); document.write( ".12x+14.4-.06x=19.2
\n" ); document.write( ".12x-.06x=19.2-14.4
\n" ); document.write( ".06x=4.8
\n" ); document.write( "x=4.8/.06
\n" ); document.write( "x=80 pounds of soybeans is used.
\n" ); document.write( "240-80=160 pounds of cornmeal is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".12*80+.06*160=.08*240
\n" ); document.write( "9.6+9.6=19.2
\n" ); document.write( "19.2=19.2
