Problema Solution
A chef is using 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
220
milliliters of a dressing that is
10%
vinegar. How much of each brand should she use?
Answer provided by our tutors
let
x = ml of the first brand (9% vinegar)
y = ml of the second brand (14% vinegar)
The chef wants to make 220 milliliters of a dressing that is 10% vinegar:
x + y = 220
0.09x + 0.14y = 0.10*220
by solving the above system of equations we find:
x = 176 ml
y = 44 ml

she should use 176 ml of the first brand and 44 ml of the second brand.
