A chef is using a mixture of two brands of Italian dressing.
\n" ); document.write( " The first brand contains 5% vinegar, and the second brand contains 12% vinegar.
\n" ); document.write( " The chef wants to make 350 milliliters of a dressing that is 8% vinegar.
\n" ); document.write( " How much of each brand should she use?
\n" ); document.write( ":
\n" ); document.write( "let v = the amt of 12% vinegar
\n" ); document.write( "then
\n" ); document.write( "(350-v) = amt of 5%
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation using decimal equiv of %
\n" ); document.write( ".12v + .05(350-v) = .08(350)
\n" ); document.write( ".12v + 17.5 - .05v = 28
\n" ); document.write( ".12v - .05v = 28 - 17.5
\n" ); document.write( ".07v = 10.5
\n" ); document.write( "v = 10.5/.07
\n" ); document.write( "v = 150 ml of the 12% vinegar
\n" ); document.write( "then
\n" ); document.write( "350 = 150 = 200 ml of the 5% \n" ); document.write( "
