Soybean meal is 12% protein. Cornmeal is 6% protein.
\n" ); document.write( " How many pounds of each should be mixed to get a 240 pound mixture that is 10% protein?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 12% protein
\n" ); document.write( "then
\n" ); document.write( "(240-x) = amt of 6% protein
\n" ); document.write( ":
\n" ); document.write( "At typical mixture equation:
\n" ); document.write( ".12x + .06(240 - x) = .10(240)
\n" ); document.write( ".12x + 14.4 - .06x = 24
\n" ); document.write( ".12x - .06x = 24 - 14.4
\n" ); document.write( ".06x = 24 - 14.4
\n" ); document.write( ".06x = 9.6
\n" ); document.write( "x = 9.6/.06
\n" ); document.write( "x = 160 lb of soy meal
\n" ); document.write( "and
\n" ); document.write( "240 - 160 = 80 lb of corn meal
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution
\n" ); document.write( ".12(160) + .06(80) = .10(240) \n" ); document.write( "

\n" );
