[Answer]Adults = 9 * 11 = 99. Children = 7 * 7 = 49. Difference: 99 - 49 = $50. The adults' tickets cost $50 more than the children's tickets. The answer is 50.

[Question]Chip takes 2 pages of notes every day, 5 days a week, for each of his 5 classes. His notebook paper comes in packs of 100 sheets of paper per pack. After 6 weeks, how many packs of notebook paper will Chip use?
[Answer]He takes 2 pages of notes every day for each of his 5 classes so that's 2 * 5 = 10 pages of notes. He takes 10 pages of notes every day for 5 days so that's 10 * 5 = 50 pages of notes. If he takes 50 pages of notes every week for 6 weeks that's 50 * 6 = 300 pages of notes. His notebook paper comes 100 pages per pack and he has taken 300 pages of notes so he used 300 / 100 = 3 packs of notebook paper. The answer is 3.

[Question]Jamie knows that once she has any more than 32 ounces of liquid she has to use the bathroom, and her teacher said that no one can use the bathroom during the math test. She remembers that she had a cup of milk at lunch and a pint of grape juice at recess. How many ounces can she drink from her water bottle during the test before she'd have to go to the bathroom? (A cup equals 8 ounces and a pint equals 16 ounces.)
[Answer]Jamie has had 24 ounces because 8 plus 16 equals 24. She can drink 8 ounces because 32 - 24 equals 8. The answer is 8.

[Question]The Parker family needs to leave the house by 5 pm for a dinner party. Mrs. Parker was waiting to get into the bathroom at 2:30 pm. Her oldest daughter used the bathroom for 45 minutes and her youngest daughter used the bathroom for another 30 minutes. Then her husband used it for 20 minutes. How much time will Mrs. Parker have to use the bathroom to leave on time?
[Answer]
Between 2:30 pm and 5:00 pm, there are 2.5 hours. There are 60 minutes in an hour, so 2.5 hours x 60 = 150 minutes. Her family was in the bathroom 45 + 30 + 20 = 95 minutes. Mrs. Parker has 150 minutes 95 minutes = 55 minutes in the bathroom. The answer is 55.
