Question

George needs flour to make bread and cookies. He used 3 cups of flour for the bread. He need 112 cups of flour for each batch of cookies. George has a total of 12 cups of flour. Select the equation that represents this scenario where x is the number of batches of cookies.

Answer 1

12 = 3 + 1 1/2x

Number of batches of cookies = 6

Explanation:

Total cups of flour = 12 cups

Flour needed for bread = 3 cups

Flour needed for each batch of cookies = 1 1/2 cups

Number of batches of cookies = x

12 = 3 + 1 1/2x

12 - 3 = 1 1/2x

9 = 3/2x

x = 9 ÷ 3/2

= 9 × 2/3

= 18/3

x = 6

Number of batches of cookies = 6
