Question

A movie ticket costs $7.50. A group of friends each buy a movie ticket and a popcorn combo. Write an expression for how much the friends spent altogether.

Answer 1

If the ticket costs $7.50, let
`p` be the price of the popcorn.

So, each of the friends spends

`7.50+p`

dollars for the ticket and the popcorn.

Now, if the group of friends is composed by
`n` people, they spend altogether

`n(7.50+p)`

dollars.
