Q: A man is purchasing a pair of sneakers at a club store where he receives a membership discount of 10% off any purchase. In addition to the membership discount, the man also has a coupon for $10 off any pair of sneakers. If the man wants to purchase a $120 pair of sneakers and the membership discount must be applied after the coupon, how much will he pay for the sneakers after using both the coupon and membership discount?
A: The coupon is applied first, which reduces the cost of the sneakers to 120 - 10 = $110. Next, the 10% discount leads to a reduction in price of 110 * 0.1 = $11. Therefore, the final price the man must pay is 110 - 11 = $99. The answer is 99.
Question: Ashley wants a champagne toast at her wedding. She wants to serve 2 glasses of champagne to each of her 120 wedding guests. 1 bottle of champagne has 6 servings. How many bottles of champagne will she need?
Answer: She wants to serve 2 glasses of champagne to each of her 120 wedding guests so that's 2 * 120 = 240 servings. Each bottle holds 6 servings and she needs 240 servings so that's 240 / 6 = 40 bottles of champagne. The answer is 40.
[Question]The number of students in Kylie's class is 50. In a particular test, ten students scored 90 marks, 15 scored ten marks fewer than the first ten students, and the rest scored 60 marks each. What are the average marks for the whole class?
[Answer]The total marks for the first ten students are 90 * 10 = 900 marks. The 15 students who scored ten marks fewer than the first ten had 90 - 10 = 80 marks each. The total marks for the following 15 students are 15 * 80 = 1200 marks. The total number of students who scored above sixty is 10 + 15 = 25. If 50 students were present in the class, those who scored sixty are 50 - 25 = 25. If 25 students scored 60, then their total marks are 60 * 25 = 1500 marks. The whole class scored a total of 1500 + 1200 + 900 = 3600 marks. The average for the class is 3600 / 50 = 72 marks. The answer is 72.
Q: Diane shows Sarah a game that deciphers at what age she will marry based on her name and current age. Sarah is 9 years old. The game consists of adding the number of letters in the player's name plus twice the player's age. According to the game, at what age will Sarah get married?
A: Sarah's name has 5 letters, so the first number to add is 5. The second number is twice Sarah's age, so it is 2 * 9 = 18. Adding the numbers together, the game predicts that Sarah will get married at 5 + 18 = 23 years old. The answer is 23.
Question: John and his two brothers decide to split the cost of an apartment. It is 40% more expensive than John's old apartment which costs $1200 per month. How much does John save per year by splitting the apartment compared to living alone?
Answer:
His old apartment cost 1200 * 12 = $14,400 per year. His new apartment 1200 * 1.4 = $1680 per month. That means it cost 1680 / 3 = $560 per month. So it cost 560 * 12 = $6720. So he saves 14400 - 6720 = $7680. The answer is 7680.
