Answer:
14
Explanation:
First, take away the 8 cookies that were not part of the 3 boxes.
(50 - 8 = 42)
Now we know that 3 boxes of cookies can hold 42 total cookies. However, we need to know how much cookies 1 box can hold. If the 42 cookies are divided evenly between the 3 boxes, our equation would look like this:
42/3 = 14
Therefore, the answer is 14 cookies in each box.
