Soymeal is 12% protein and cornmeal is 6%. How many pounds of each should be mixed together to get 240 pound mixture that is 7% protein?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of Soymeal required
\n" ); document.write( "The total is given as 240 lb, therefore:
\n" ); document.write( "(240-x) = amt of cornmeal required
\n" ); document.write( ":
\n" ); document.write( ".12x + .06(240-x) = .07(240)
\n" ); document.write( ":
\n" ); document.write( ".12x + 14.4 - .06x = 16.8
\n" ); document.write( ":
\n" ); document.write( ".12x - .06x = 16.8 - 14.4
\n" ); document.write( ":
\n" ); document.write( ".06x = 2.4
\n" ); document.write( "x = \"2.4%2F.06\"
\n" ); document.write( "x = 40 lb of Soymeal
\n" ); document.write( "Then
\n" ); document.write( "240 - 40 = 200 lb of corn meal
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution in the equation
\n" ); document.write( ".12(40) + .06(200) = .07(240)
\n" ); document.write( " 4.8 + 12 = 16.8 confirms our solutions \n" ); document.write( "
\n" );
