Answer: 3 different ways

Explanation:

We will find all the different methods you could buy 60 cookies using groups of 10 or 30. We will use addition.

[1] 60 = 10 + 10 + 10 + 10 + 10 + 10

[2] 60 = 30 + 30

[3] 60 = 30 + 10 + 10 + 10

You can buy 60 cookies in 3 different ways. This does not include the exact order in which the packages are bought, only the packages bought.
