Determine the change
First, we need to determine the total amount spent on movie ticket.
The question does not state whether I pay for my friend's ticket.

Add this amount to the amount spent on popcorn


To get the Change, we have to deduct the total amount spent from the amount given by mom


Hence:
The change is $10.25
