Write a function to describe the following
scenario.
A movie theatre runs a special promotion where
each person pays for an all-day ticket and
for each item at the concession stand. How
much does each person pay for their day at the
movie theatre?

To describe this scenario using a function, we can let represent the number of items purchased at the concession stand. Each person pays a flat rate of $10 for the ticket, plus $2 for each item they buy. Therefore, the function that represents the total cost for a person attending the movie theatre can be written as:

This means that for every item bought at the concession stand, they spend an additional $2, added to the fixed ticket price of $10.

Now, if you’re planning a movie day, don’t forget about the delicious popcorn! It’s a must for the full experience, and it’ll make your movie-watching even more enjoyable. So, calculate that total carefully to make sure you’ve got enough cash!
