Question: Joe and Adam built a garden wall with three courses of bricks. They realized the wall was too low and added 2 more courses. If each course of the wall had 400 bricks, and they took out half of the bricks in the last course to allow easy checkup of the garden, calculate the total number of bricks the wall has.
Answer: When they added two more courses for the wall, the number of courses became 3 + 2 = 5. Since each course has 400 bricks, the total number of bricks for 5 courses is 5 * 400 = 2000. To allow for an easy checkup of the wall, they removed 1 / 2 * 400 = 200 bricks from the last course of the wall. In total, the wall has 2000 - 200 = 1800 bricks. The answer is 1800.
[Question]Julia has a parrot and a rabbit. She buys food for both of the animals for $30 in total a week. Julia has the rabbit for 5 weeks, and the parrot for 3 weeks. How much money did Julia already spend on food for her animals, if the weekly cost of the rabbit food is $12?
[Answer]If the rabbit food costs $12 a week, then the parrot food costs $30 - $12 = $18 a week. Julia has the parrot for 3 weeks, so she spent 3 weeks * $18 / week = $54 on her. The rabbit is her only for 5 weeks, so she spent 5 weeks * $12 / week = $60 on him. In total, Julia spent $54 + $60 = $114 on food for her animals. The answer is 114.
Q: There were students from three different schools taking part in a debate organized by the town's mayor on a stage. The first school had twice as many students as the second school, and the second school had 40 more students than the third school. If the third school had 200 students, and after the debate was over, every student shook the mayor's hand, calculate the total number of students who shook the mayor's hand on the stage.
A: If the third school had 200 students, and the second school had 40 more students than the third school, the second school had 200 + 40 = 240 students. The third and second schools had 240 + 200 = 440 students on stage taking part in the debate. Since the first school had twice as many students as the second school, and the second school had 240 students, the first school had 240 * 2 = 480 students on stage taking part in the debate. If after the debate was over, every student at the stage shook the mayor's hand, the number of students who shook the mayor's hand is 480 + 440 = 920 students. The answer is 920.
Question: Claire won a $100 gift card to her favorite coffee shop. She wants to treat herself to a latte that cost $3.75 and a croissant for $3.50 every morning for a week. She also plans to buy 5 cookies that cost $1.25 each. How much money will be left on her card after a week of coffee and pastry?
Answer: Every day she buys $3.75 latte and $3.50 croissant for a total of 3.75 + 3.50 = $7.25 per day. If she spends $7.25 a day for 7 days she will spend 7.25 * 7 = $50.75 in one week. If she buys 5 cookies at $1.25 each she will spend 5 * 1.25 = $6.25. Her gift card is for $100 and she spends $50.75 and an additional $6.25 that will leave her with 100 - 50.75 - 6.25 = $43.00 on her gift card. The answer is 43.

He sold 2 * 25 = 50 amulets. So he made 40 * 50 = $2000. The faire took 2000 * .1 = $200. So he kept 2000 - 200 = $1800. The amulets cost 50 * 30 = $1500 to make. So he had a profit of 1800 - 1500 = $300. The answer is 300.
