Answer 2

Answer: 4 quarts.

Explanation:

Given data:

Amount of dry ingredients = 5 quarts.

Amount of water in the mixture = 2 quarts.

Solution:

Let’s a represent the amount of dry ingredients.

Let b represent the amount of water

For first Batch

a/b = 5/2.

b = 2/5a ....... equation 1

For second Batch

a= 10

substitute a into equation 1 to solve for b

b = 2/5(10)

b = 4.

The ratio for batch b = 10/4.

Zahara needs to add 4 quarts of water to the mixture.
