Simple Expression Help

Okay, so I'm re-visiting basic stuff cause I'm gonna have an exam on this basic stuff in a few days.

I have to write an expression with x.

Tickets for a baseball game are sold for $7.50 each and so far $1500 worth has been sold, write an expression with x.

I put: $1500 + $7.50x That sound right?

Thanks

What does represent? Can you write the exact question? It doesn't really make sense at the moment.

Here I'll give you a screenshot.

As you can see, the right on the chart there's a space open that I can enter the answer that I put in the first post, just wanted to make sure it's right since I haven't done this in a while.

Yeah, your expression is fine then.

Indeed it was, thanks.
