Soybean meals is 18% protein; cornmeal is 9% protein. How many pounds of each should be mixed together in order to get 360-1b mixture that is 11% protein.\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "Soybean meals is 18% protein; : x lb
\n" ); document.write( "cornmeal is 9% protein. : 360-x lb
\n" ); document.write( "360-1b mixture that is 11% protein.
