Making the assumption that only soybean meal and cornmeal are added to the mixture. We get x = amount of soybean meal and y = amount of cornmeal
\n" ); document.write( "x+y = 320.
\n" ); document.write( "solving for y we get y =320 -x.\r
\n" ); document.write( "\n" ); document.write( "We also know that 0.16(x) + .08(y) = 320*(.13)
\n" ); document.write( ":
\n" ); document.write( ".16x + 0.08(320-x) = 41.6
\n" ); document.write( ":
\n" ); document.write( "0.08x + 25.6 = 41.6
\n" ); document.write( ":
\n" ); document.write( "0.08x = 16
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28x+=+200%29\"pounds of soybean
\n" ); document.write( ":
\n" ); document.write( "y=320-x:\"highlight%28y=320-200=120%29\"pounds of cornmeal \r
