The question is looking for the amount of boxes (24 per box) needed for the event (300). If you multiply 24 by each number, you would be able to find the answer. 24*11 = 264, so that isn’t enough. 24*12 = 288, and that also isn’t enough. But if you do 24*13, you get 312, which gives you more than enough cupcakes for the event. So the answer is 13.
