: Soybean meal is 60% protein, cornmeal is 8% protein.
\n" ); document.write( " How many pounds of each should be mixed together in order to get 320 pound mixture that is 9% protein?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of soy meal required
\n" ); document.write( "It gives total mixture as 320 lb, therefore:
\n" ); document.write( "(320-x) = amt of corn meal
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation:
\n" ); document.write( ".60x + .08(320-x) = .09(320)
\n" ); document.write( ":
\n" ); document.write( ".60x + 25.6 - .08x = 28.8
\n" ); document.write( ":
\n" ); document.write( ".60x - .08x = 28.8 - 25.6
\n" ); document.write( ":
\n" ); document.write( ".52x = 3.2
\n" ); document.write( "x = \"3.2%2F.52\"
\n" ); document.write( "x = 6.154 lb of soy meal
\n" ); document.write( "then
\n" ); document.write( "320 - 6.154 = 313.846 lb of cornmeal
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the equation
\n" ); document.write( ".6(6.154) + .08(313.846) = .09(320)
\n" ); document.write( "3.6924 + 25.108 = 28.8 \n" ); document.write( "
\n" );
