Problema Solution
A cook needs to mix a regular ranch dressing containing 41% fat with a light ranch dressing containing 31% fat to result in 3 cups of a dressing containing 35% fat. How many cups of each kind of dressing should be mixed?
Answer provided by our tutors
let
x = the cups of the 41% fat dressing
y = the cups of the 31% fat dressing
x + y = 3
0.41x + 0.31y = 0.35*3
by solving the system of equations we find
x = 1.2 cups
y = 1.8 cups
