\n" ); document.write( "a chef is going to use a mixture of two brands of Italian dressing. the first brand contains 9% vinegar, and the second brand contains 14%vinegar. the chef wants to make 270 milliliters of a dressing that is 11%vinegar. how much of each brand should she use?
\n" ); document.write( "
Let amount of 9% to be mixed, be N
\n" ); document.write( "Then amount of the 14% concentration to be mixed = 270 - N
\n" ); document.write( "We then get: .09N + .14(270 - N) = .11(270)
\n" ); document.write( " .09N + 37.8 - .14N = 29.7
\n" ); document.write( " .09N - .14N = 29.7 - 37.8
\n" ); document.write( " - .05N = - 8.1
\n" ); document.write( "Amount of 9% to be mixed, or
\n" ); document.write( "You should now be able to determine the amount of the 14% to mix!! \n" ); document.write( "
\n" );
