Question

A) 2
B) 3
C) 4
D) 5

Answer 1

To find the number of packages of vanilla wafers John's mother needs to purchase, we divide the total number of cookies the children will eat by the number of cookies per package. The answer is b. 3 packages of vanilla wafers.

Step-by-step explanation:

To calculate the number of packages of vanilla wafers John's mother needs to purchase, we need to find the total number of cookies the children will eat and divide that by the number of cookies in each package. The total number of cookies the children will eat is 15 children x 4 cookies = 60 cookies. The number of packages of vanilla wafers needed is 60 cookies ÷ 24 cookies per package = 2.5 packages.

Since we can't purchase half a package, John's mother needs to purchase 3 packages of vanilla wafers.
