Achef is going to use a mixture of two brands of italian dressing. the first brand contains 7% vinegar, and the second brand contains 12% vinegar. the chef wants to make 270 milliliters of a dressing that is 9% vinegar. how much of each brand should she use?

There is 162 ml of first brand and 108 ml of second brand.

Step-by-step explanation:

Since we have given that

Percentage of vinegar that the first brand contains = 7%

Percentage of vinegar that the second brand contains = 12%

Percentage of vinegar in mixture = 9%

Total amount of dressing = 270 ml

We will use "Mixture and Allegation":

First brand                  Second brand

     7%                                12%

                       9%

--------------------------------------------------------

12%-9%             :                9%-7%

 3%                   :                    2%

So, ratio of first brand to second brand in a mixture is 3:2.

So, Amount of first brand she should use is given by

Amount of second brand she should use is given by

Hence, there is 162 ml of first brand and 108 ml of second brand.
