To solve this, we'd divide 54 by 3:\[\frac{ $54 }{ 3 } = $18\] So, $18 is the cost of one ticket. Since we're looking for 7, we'd times $18 by 7:\[$18 * 7 = ?\] Think you can get the answer?

its A

To figure this out, what you need to do is figure out how much money 1 ticket costs. And to do that, you divide \[$54\div3\] Now, because you know the amount of 1 ticket, you can multiply by 7 to find the amount of 7 tickets.

Yep, that's your answer. But don't forget the $ sign. $126.
