The admission fee to the Fair is $7.50

The rides cost 50c each.

Let x be the number of rides she can take.

You can express her expenses in the fair as an equation:

C= total cost

C=7.50+0.5x → from this equation you can calculate how many rides she will be able to get on.

If she has a total of $23 to spend, then the number of rides can be calculated as:


\begin{gathered} C=7.50+0.5x \\ 23=7.50+0.5x \\ 23-7.5=0.5x \\ 15.5=0.5x \\ x=(15.5)/(0.5) \\ x=31 \end{gathered}

With $23 she will be able to go on 31 rides.
