Final answer:
The school should buy 8 boxes of cookies to get a total of 64 cookies, as each box contains 8 cookies.
Step-by-step explanation:
The question asks how many boxes of cookies a school should buy if they want to purchase a total of 64 cookies and the cookies are sold in boxes of 8.
To solve this, we can use a simple division: Number of boxes needed = Total number of cookies ÷ Number of cookies in each box.
Number of boxes needed = 64 cookies ÷ 8 cookies/box = 8 boxes.
Therefore, the school should buy 8 boxes of cookies to have a total of 64 cookies for the party.
