Question
Ana has 36 cupcakes to put into boxes for a bake sale. She wants to put an equal number of cupcakes in each box. There are 9 boxes. Ana uses the division equation below to find how many cupcakes she should put in each box.
To find the missing number, Ana knows she can think about the problem in a different way. She uses the addition equation below.

To solve the problem correctly, Ana needs to determine how many cupcakes she can put in each box by dividing the total number of cupcakes by the number of boxes. She has 36 cupcakes and 9 boxes, so the correct operation is \( 36 \div 9 = 4 \).
In the context of what Ana did wrong, let's evaluate the answer choices based on the given explanation:
A. Ana added ___, She should have added ___. - This doesn't address her mistake properly, as the error is not in adding but in misunderstanding how to calculate cupcakes per box.
B. Ana added incorrectly. Adding ___ does not equal 36. - This option also doesn't properly explain what Ana's miscalculation was regarding dividing instead of adding.
C. Ana added ___. She should have multiplied ___. - This is also incorrect, as she should not be adding or multiplying; she should be dividing.
D. Ana divided ___. She should have divided ___. - This option is correct in the sense that it acknowledges that Ana needed to divide but doesn't clarify what she did wrong prior to this.
However, based on her final assertions that she thought she should put 27 cupcakes in each box, this is indeed a misunderstanding of dividing the total cupcakes. The most relevant choice that aligns with her mistake is ***C*** because adding would not lead to the correct quantity for boxes relative to cups.
So, to summarize, the correct answer isn't perfect, but if we adapt according to her original problem of reaching a cupcake quantity of 27 erroneously, it seems more aligned with option C, as it references the relationship between addition/multiplication errors regarding grouping differently instead of simplicity.
Thus the best and most relevant choice would be ***C***.
