.18x+.09(360-x)=.13*360
\n" ); document.write( ".18x+32.4-.09x=46.8
\n" ); document.write( ".09x=46.8-32.4
\n" ); document.write( ".09x=14.4
\n" ); document.write( "x=14.4/.09
\n" ); document.write( "x=160 lb. of soybeans is used.
\n" ); document.write( "360-260=200 lb. of cornmeal is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".18*180+.09*300=46.8
\n" ); document.write( "28.8+18=46.8
\n" ); document.write( "46.8=46.8
\n" ); document.write( "
