.16x+.08(320-x)=.14*320
\n" ); document.write( ".16x+25.60-.08x=44.8
\n" ); document.write( ".08x=44.8-25.60
\n" ); document.write( ".08x=19.2
\n" ); document.write( "x=19.2/.08
\n" ); document.write( "x=240 lbs. of soybean are used.
\n" ); document.write( "320-240=80 lbs. of cornmeal is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".16*240+.08*80=.14*320
\n" ); document.write( "38.4+6.4=44.8
\n" ); document.write( "44.8=44.8
\n" ); document.write( "
