A chef is going to use a mixture of two brands of Italian dressing. The first brand contains
vinegar, and the second brand contains
vinegar. The chef wants to make
milliliters of a dressing that is
vinegar. How much of each brand should she use?
Set up an equation that matches the sentences of the problem:
It is given that, the aim of a chef is to use a mixture of two brands (First and second) of Italian dressing.
The first brand contains 7% of vinegar.
Denote the amount of the first brand as F.
The second brand contains 12% of vinegar.
Denote the amount of the second brand as S.
The chef wants to make 260 milliliters of a dressing using the first and second brands.
That is, F + S = 260.
Furthermore, it is also stated that, the total mixture should contain 8% vinegar.
That is, 0.07F + 0.12S = 0.08*260.
Obtain the amount of first brand and second brand that have to be used:
The amount of first brand and second brand that have to be used is obtained from the calcul...
