Question

3 Quartz of 10% butterfat is mixed with some unknown amount of 3% whole milk. If there are 8 quarts of the total mixture, how many quarts of whole milk were used?

What is the % fat In the final mixture?

Answer 1

The total amount is 15% I think I had this same question but different numbers

Answer 2

Correct answer: Whole milk 5 quartz and 5.625%

Explanation:

When we subtract from the total mixture 8 the quantity 3 of the butterfat we will get 5 quartz of the whole milk.

We will solve the problem using the following equation:

3 · 10 + 5 · 3 = 8 · x ⇒ 30 + 15 = 8 x ⇒ 8 x = 45

x = 45 / 8 = 5.625%

x = 5.625%
