Q: Fiona and Casey share the hoodies they own. Between the two of them, they own eight hoodies. Casey owns two more than Fiona. How many hoodies does Fiona own?
A: Let H be the number of hoodies Fiona owns. Casey owns H + 2 hoodies. Together, they own H + H + 2 = 2H + 2 = 8 hoodies. Thus, 2H = 8 - 2 = 6 hoodies. Therefore, Fiona owns H = 6 / 2 = 3 hoodies. The answer is 3.
Question: The Dark Lord needs to transport 1200 pounds of swords to the Enchanted Forest for a battle with the elves. He has 10 squads of 8 orcs each. How many pounds of swords does each orc have to carry?
Answer: First find how many orcs there are total by multiplying the number of orcs per squad by the number of squads: 8 orcs / squad * 10 squads = 80 orcs. Then divide the total amount of swords by the number of orcs to find the amount of swords per orc: 1200 pounds / 80 orcs = 15 pounds / orc. The answer is 15.

Q: It's exam season and Tristan has several exams to prepare for. On Monday, he studies for 4 hours then studies for twice this long on Tuesday. On Wednesday, Thursday, and Friday he studies for 3 hours each day. He wants to study for a total of 25 hours over the week and divides the remaining amount of study time evenly between Saturday and Sunday. How many hours does Tristan spend studying on Saturday?
A:
On Tuesday, Tristan studies twice as long as he did on Monday and this amounts to 4 hours * 2 = 8 hours. So in the first 5 days of the week, he studies for a total of 4 hours Monday + 8 hours Tuesday + 3 hours Wednesday + 3 hours Thursday + 3 hours Friday = 21 hours. He therefore has 25 planned hours 21 used hours = 4 hours left to study. As he splits his time evenly over 2 days, he spends 4 hours / 2 = 2 hours studying on Saturday. The answer is 2.
