Mrs. Lopez and her family are going to the movie theatre. Adult tickets are $11. Children's tickets (ages 3-12) are $8. Senior citizen's tickets (ages 60+) are $9. Mrs. Lopez needs to buy movie tickets for her husband, herself, her parents (ages 72 and 75), and her three children (ages 7, 10, 14). How much money does she need to buy everyone's tickets? Let's think first. Chain of thought:
Mrs. Lopez needs to buy two adult tickets for $11 x 2 = $22. She needs to buy two senior citizen tickets for $9 x 2 = $18. She needs to buy three children's tickets for $8 x 3 = $24. For everyone's tickets, Mrs. Lopez needs to spend $22 + $18 + $24 = $64 for seven tickets.
Therefore, the answer is 64.
