Question

For every 3 dozen cookies, a bakery uses 8 cups of butter. How many dozen of cookies could you make with 20 cups of butter?

Answer 1

7 1/2 dozen of cookies

Explanation:

If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;

3 dozens cookies = 8 cups of butter

x cups of cookies = 20 cups of butter

Cross multiply

8*x = 3 * 20

8x = 60

x = 60/8

x = 7 4/8

x = 7 1/2

Hence you will need 7 1/2 dozen of cookies
