Question

Barbara bought 5 movie tickets for $30. If she bought 9 tickets how much would it cost?

Answer 1

$54
30 divided by 5 is 6. then 6 times 9 is 54

Answer 2

$ 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
