2. Soybean meal is 18% protein: cornmeal is 9% protein. How many pounds of each should be mixed together in order to get 360-ld mixture that is 17% protein.
\n" ); document.write( "Pounds of cornmeal that should be in mixture?
\n" ); document.write( "Pounds of soybean meal should be in mixture?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "first mixture + second mixture = total mixture\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.18x + 0.09x = 360(0.17)\r
\n" ); document.write( "\n" ); document.write( "0.18x + 0.09x(360 - x) = 0.17(360)\r
\n" ); document.write( "\n" ); document.write( "Can you take it from here?\r
\n" ); document.write( "\n" ); document.write( "
