Question

Melissa made 326 cupcakes. If upto 4 cupcakes can be packed into a box, how many boxes are needed to pack all of the cupcakes?

• A. 85
• B. 80
• C. 81
• D. 82

Answer 1

The correct option is D 82

Total number of cupcakes = 326
Number of cupcakes in a box = 4
To find the number of boxes needed, let's divide 326 by 4.

$$\begin{array}{c}81\\ 4326\\ -\underset{–}{32}2\\ 06\\ -\underset{–}{4}\\ 2\end{array}$$Thus, we have a quotient of 81 and a remiander of 2.
So, after putting the cupcakes in 81 boxes, 2 cupcakes would be left out. So we need 1 more box to put those 2.
=> total number of boxes needed = 81 + 1 = 82
