Final answer:
To find the change you receive, subtract the cost of the movie ticket and popcorn from the total amount paid.
Step-by-step explanation:
To complete a verbal model for the problem, we can say:
You purchase a movie ticket for $8.25 and popcorn for $3.99. You pay a total of $10 in bills. The change you receive is the difference between the total amount you paid and the cost of the movie ticket and popcorn combined.
The change you receive is calculated as:
Change = Total amount paid - Cost of movie ticket - Cost of popcorn
Change = $10 - $8.25 - $3.99
