How can Transformers be worldwide overall all time movie with big profit, when the movie ticket is $18?

I went for the matinee... they would charge me $11 or $13... I was like, what's time is it? They are charging me $11 to see this movie at 1pm? Did they overcharged me?How can Transformers be worldwide overall all time movie with big profit, when the movie ticket is $18?Ticket prices are different everywhere you go.How can Transformers be worldwide overall all time movie with big profit, when the movie ticket is $18?They charge what ever they want....I dont understand how they can say one movie outsold another movie from 15 years ago either because 15 years ago it was $10 less a ticket....
