[Question]: Kiarra is twice as old as Bea. Job is 3 times older than Bea. Figaro is 7 years older than Job. Harry is half as old as Figaro. If Kiarra is 30, how old is Harry?
[Answer]: Bea is 30 / 2 = 15 years old. Job is 15 * 3 = 45 years old. Figaro is 45 + 7 = 52 years old. Harry is 52 / 2 = 26 years old.
So the answer is 26.

[Question]: An elementary school teacher is making Halloween goodie bags for her class. She wants the bags to be personalized, so she surveys her students asking whether they'd like a vampire-themed bag or a pumpkin-themed bag. Of her 25 students, 11 indicate they want the vampire-themed bag and 14 indicate they want the pumpkin-themed bag. The store the teacher shops at sells packs of 5 of each theme at a price of $3 per package, as well as individual bags of each theme at a price of $1 each. What is the least amount of money the teacher can spend on the bags if she buys every student the theme they requested?
[Answer]: Because it is cheaper to buy the packs of 5, the teacher should satisfy the 11 students who want the vampire theme with 2 packs of 5 and 1 individual bag. This will cost the teacher 2 * 3 + 1 * 1 = $7. Similarly, the 14 students who want a pumpkin - themed bag can be satisfied by 2 packs of 5 and 4 individual bags at a cost of 2 * 3 + 4 * 1 = $10. Therefore, the teacher must spend 7 + 10 = $17.
So the answer is 17.

[Question]: A jug needs 40 cups of water to be full. A custodian at Truman Elementary School has to fill water jugs for 200 students, who drink 10 cups of water in a day. How many water jugs will the custodian fill with cups of water to provide the students with all the water they need in a day?
[Answer]:
Since each student needs 10 cups of water per day and there are 200 students, the custodian has to provide 200 * 10 = 2000 cups of water. A jug of water needs 40 cups to be full, so 2000 cups of water will fill 2000 / 40 = 50 jugs.
So the answer is 50.
