Question

David baked 78 cookies for a bake sale. he set aside 12 cookies to share with volunteers. the remaining cookies are bag with three cookies in each bag. how many bags does david need

Answer 1

He would need 22 bags because since he took away 12 cookies for the volunteers, there would only be 66 cookies left for the sale. So when you divide that by the 3 bags, it would turn out that he needs 22 bags.

Answer 2

78-12+66
66/3=22

He needs 22 bags
