You can put this solution on YOUR website!
let the number of pounds of soybean and cornmeal be s and c respectively
\n" ); document.write( "we know there are 360 pounds altogether
\n" ); document.write( ":
\n" ); document.write( "s+c=360................eq 1
\n" ); document.write( ".18s+.09c=.11(360).....eq 2
\n" ); document.write( ":
\n" ); document.write( "lets rewrite eq 1 to s=360-c and take that value and plug it into eq 2
\n" ); document.write( ":
\n" ); document.write( ".18(360-c)+.09c=39.6
\n" ); document.write( ":
\n" ); document.write( "64.8-.18c+.09c=39.6
\n" ); document.write( ":
\n" ); document.write( "-.09c=-25.5
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28c=280%29\"pounds of cornmeal
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28s=360-c=360-280=80%29\"pounds of soybean meal\r
\n" ); document.write( "\n" ); document.write( "This makes alot of sense because the cornmeal is 9% protein which is much closer to the final mixture of 11% protein that the soybean which is 18%. So it definitely fits that we use alot more of the cormeal mix to reach our 11% protein goal
\n" ); document.write( "
\n" );
