Cookies are sold singly or in packages of 3 or 9. With this packaging, how many ways can you buy 18 cookies?

1 answer:

8 0

I believe 5 different ways. The options being two packs of 9-one pack of 9 and 3 packs of 3- 1 pack of 9, 2 packs of 3 and 3 singles- one pack of 9, one pack of 3, and 6 singles- and then one pack of 9 and 9 singles.
Hope this helped!
