Answer:

$ 54

Explanation:

Barbara bought :

5 tickets ⇒ $ 30

And now let the costs of 9 tickets be x :

9 tickets ⇒ $ x

So,

5 tickets ⇒ $ 30

9 tickets ⇒ $ x

Now use cross multiplication to find the value of x :

5 x = 9 × 30

5 x = 270

Now divide both sides by 5.

x = $ 54

Hope this helps you :-)

Let me know if you have any other questions :-)
