[Question]Alex was having a cookout Friday night and planned to serve burgers to his guests. He planned to cook 3 burgers for each guest and had invited 10 friends over. 1 of his friends didn't eat meat and said they would bring their own food. Another one of his friends didn't eat bread and would not need the buns. The burger buns came 8 to a pack. How many packs of buns did Alex need to buy?
[Answer]He invited 10 friends but he didn't need to cook for 1 of his friends so that left 10 - 1 = 9 friends to cook for. He was cooking 3 burgers per 9 guests so 3 * 9 = 27 burgers. He needed 27 burger buns but 1 guest wouldn't eat the buns so now he needs 27 - 3 = 24. He will need to buy 24 buns and they come 8 to a pack so he needs 24 / 8 = 3 packs of buns. The answer is 3.
Q: A few friends are making a small movie. They hire a few actors and that cost $1200. They also get food for the 50 people there. Each person gets $3 worth of food. Equipment rental costs twice as much as food and actors combined. They sold the movie for $10,000. How much profit did they make?
A: The food cost 3 * 50 = $150. So the total cost without equipment rental was 1200 + 150 = $1350. So equipment rental cost 1350 * 2 = $2700. So the total cost was 2700 + 1350 = $4050. That means they made 10000 - 4050 = $5950. The answer is 5950.

[Question]Gary counted the number of whiskers on the faces of his two cats. Princess Puff has 14 whiskers, while Catman Do has 6 less than twice the number of whiskers as Princess puff. How many whiskers does Catman Do have?
[Answer]Twice the number of whiskers as Catman Do is 14 * 2 = 28 whiskers. Catman Do has 6 less than twice the number of whiskers as Princess puff, for a total of 28 - 6 = 22 whiskers. The answer is 22.
Q: James wants to learn to become a chess grandmaster. It takes 2 hours to learn the rules. It then takes him 49 times that long to get a level of proficiency to start playing in local tournaments. After that, he devotes his life to chess and spends 100 times as much as the combined time to get proficient to becoming a master. How much total time did he spend?
A: It takes him 2 * 49 = 98 hours to go from knowing how to play to proficient. So he spends 98 + 2 = 100 hours combined on those. So it takes him 100 * 100 = 10,000 hours to become a master from proficient. So the total time was 100 + 10000 = 10,100 hours. The answer is 10100.
Question: Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks?
