Let's call the amount of 12% used, x.
\n" ); document.write( "Then the amount of 6% used would have to be 24-x (since we need 24 ounces total).
\n" ); document.write( "Here's the set up...
\n" ); document.write( ".12x + .06(24-x) = .10(24)
\n" ); document.write( "Now solve for x...
\n" ); document.write( ".12x + 1.44 - .06x = 2.4
\n" ); document.write( ".06x = .96
\n" ); document.write( "x = 16 ounces of 12%
\n" ); document.write( "24-x = 8 ounces of 6%
\n" ); document.write( "
\n" );
