Answer:
3 is the difference(remainder) of $33-$30
Explanation:
Samuel has $33
A pack of cards cost $5
The most packs Samuel can buy is 6
6*5=$30
$33-30=3
If it was my store I would have a camera in every corner of the store to get every angle. So to get the official answer I suggest you to count how many corners there are throughout the store and that will be your answer.
Hope this helps!
