Answer:
18 dozen cookies
Explanation:
To solve this problem you need to divide the total amount of sugar you have by how many cups of sugar it takes to make 3 dozen cookies.
The total amount of sugar you have is 4 cups and you need to divide this 2/3 of a cup of sugar because that's how many cups you need to make 3 dozen cookies. When you divide 4 by 2/3 you will get 6.
The number 6 is the amount of batches of the cookies you can make with the sugar. So 3 dozen of cookies equals one batch. Now to find how many dozens of cookies in total you can make you need to multiply 6 by 3 to get 18 dozen cookies.
So with 4 cups of sugar you can make 18 dozen cookies.
