Answer: she can get 27 boxes of cookies and 7 would be leftover.
Step-by-step explanation:
The total number of cookies that Amy baked is 250. She sells them in boxes of nine. Therefore, the total number of boxes containing 9 cookies each that she can get from a total of 250 cookies would be
250/9 = 27.778
This means that she can only get 27 boxes of cookies.
The number of cookies that would be left over is
250 - (27 × 9) = 250 - 243
= 7
