Q: John decides to learn how to play the piano. He buys a piano for $500. He then hires a teacher for 20 lessons at $40 per lesson but ends up getting a 25% discount. How much did everything cost?
A: The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100. The answer is 1100.
Question: Students at Highridge High earn 2 points for each correct answer during a quiz bowl If a student correctly answers all the questions in a round, the student is awarded an additional 4 point bonus. They played a total of five rounds each consisting of five questions. If James only missed one question, how many points did he get?
Answer: If James only missed one question in all five rounds of five questions, he correctly answered 5 * 5 - 1 = 24 questions. Before the bonus, James earned 24 correct answers * 2 points / answer = 48 points. Since missing one question would only disqualify him from receiving a bonus in one round, he would earn a bonus for 5 - 1 = 4 rounds. He should expect a bonus of 4 rounds * 4 points / round = 16 points. Including his bonus, James scored a total of 48 + 16 = 64 points. The answer is 66.
[Question]Teddy has 7 dogs and 8 cats. Ben has 9 more dogs than Teddy, and Dave has 13 more cats and 5 less dogs than Teddy. How many pets do all of them have combined?
[Answer]Teddy has 7 + 8 = 15 pets in total. Ben has 9 + 7 = 16 dogs, which means he has 16 pets in total. Dave has 13 + 8 = 21 cats. Dave has 7 - 5 = 2 dogs. Dave has 21 + 2 = 23 pets in total. Combined, they have 15 + 16 + 23 = 54 pets in total. The answer is 54.
Q: Avery opens a flower shop. She ties 8 bunches of flowers with 9 flowers in each bunch. How many bunches would she have if she put 12 flowers in each bunch instead?
A: She has a total of 8 * 9 = 72 flowers. Dividing them in bunches of 12 will give her 72 / 12 = 6 bunches of flowers. The answer is 6.
Question: A store owner buys clothes wholesale and adds 80% to the wholesale price to set the retail price. The retail price of a pair of pants is $36. What is the wholesale price?
Answer: Let X be the wholesale price. The retail price of a pair of pants is X + X * 80% = $36. Thus 1.8 * X = $36. Thus X = $36 / 1.8 = $20. The answer is 20.
Q: Henry took 9 pills a day for 14 days. Of these 9 pills, 4 pills cost $1.50 each, and the other pills each cost $5.50 more. How much did he spend in total on the pills?
A:
There were 9 - 4 = 5 other pills. Each of the other pills cost 1.50 + 5.50 = 7 dollars each. The 5 pills cost a total of 7 * 5 = 35 dollars. The first 4 pills cost 1.50 * 4 = 6 dollars in total. Henry spent a total of 35 + 6 = 41 dollars. The answer is 41.
