Q: A class has 500 tables and 2/5 times as many books as the number of tables in the class are on top of each table. What's the total number of books in the class?
A: If there are 2 / 5 times as many books as the number of tables in the class on top of each table, there are 2 / 5 * 500 = 200 books. Since the class has 500 tables with 200 books on top of each, there are 500 * 200 = 100000 books. The answer is 100000.
Question: Claire is scheduling her day. She has four hours to clean and two hours to cook, then divides the rest of her working day equally between crafting and tailoring. She then sleeps eight hours. If all of this takes place within one day, how many hours did Claire spend crafting?
Answer: We know Claire has spent a total of 24 hours in a day - 4 hours cleaning - 2 hours cooking - 8 hours sleeping = 10 hours crafting and tailoring. Since she split her time equally, she must have spent 10 hours * 0.5 = 5 hours crafting. The answer is 5.
[Question]Jason has a carriage house that he rents out. He’s charging $50.00 per day or $500.00 for 14 days. Eric wants to rent the house for 20 days. How much will it cost him?
[Answer]He wants to rent for 20 days and there is a deal if you rent for 14 days so that leaves 20 - 14 = 6 individual days. Each individual day is $50.00 and he will have 6 individual days for a total of 50 * 6 = $300.00. 14 days costs $500.00 and 6 days costs $300.00 for a total of 500 + 300 = $800.00. The answer is 800.
Q: It’s February 2021. Mark was born in January 1976. Graham is 3 years younger than Mark, and Graham’s sister, Janice, is 1/2 the age of Graham. How old is Janice?
A: It’s 2021 and Mark was born in 1976 so Mark is 2021 - 1976 = 45 years old. Graham is 3 years younger than Mark who is 45 so Graham is 45 - 3 = 42 years old. Janice is 1 / 2 the age of Graham who is 42 so Janice is 42 / 2 = 21 years old. The answer is 21.
