Question: Yesterday Ryan got five books from the library. They were a total of 2100 pages. His brother got one book a day that was 200 pages each. They both finished them in a week. On average, how many more pages per day did Ryan read compared to his brother?
Answer: Ryan read an average of 300 pages a day because 2100 / 7 = 300. He read 100 more pages a day on average than his brother because 300 - 200 = 100. The answer is 100.
[Question]Jenny wants to sell some girl scout cookies and has the choice of two neighborhoods to visit. Neighborhood A has 10 homes which each will buy 2 boxes of cookies. Neighborhood B has 5 homes, each of which will buy 5 boxes of cookies. Assuming each box of cookies costs $2, how much will Jenny make at the better choice of the two neighborhoods?
[Answer]First, we need to determine which neighborhood is the better choice by comparing the number of boxes sold. A has 10 houses which will buy 2 boxes each, meaning A will give Jenny 10 * 2 = 20 box sales. Neighborhood B has 5 homes which will each buy 5 boxes, meaning she will sell 5 * 5 = 25 boxes by going to that neighborhood. Since 25>20, this means Jenny should choose neighborhood B. Since Jenny earns $2 per box sold, this means she will earn 25 * 2 = 50 dollars by choosing neighborhood B. The answer is 50.
Q: Emma and Briana invested some capital into a business. Emma's investment is supposed to yield 15% of the capital annually while Briana's should yield 10% annually. If Emma invested $300 and Briana invested $500, what will be the difference between their return-on-investment after 2 years?
A: 15% of $300 is (15 / 100) * $300 = $45. Emma will earn an annual ROI of $45 for 2 years for a total of $45 * 2 = $90. 10% of $500 is (10 / 100) * $500 = $50. Briana will earn an annual ROI of $50 for 2 years for a total of $50 * 2 = $100. The difference between their ROI after 2 years is $100 - $90 = $10. The answer is 10.
Question: The total age of the people in Kaydence's family is 200. If Kaydence's father is 60 years old, Kaydence's mother 2 years younger than Kaydence's father, Kaydence's brother 1/2 the age of Kaydence's father, and Kaydence's sister 40 years old, how old is Kaydence?
Answer: If Kaydence's father is 60 years old, her mother is 60 - 2 = 58 years old. The total age of the mother and father is 60 + 58 = 118 years. Kaydence's brother is half the father's age, which is 1 / 2 * 60 = 30 years. The total age of Kaydence's father, mother, and brother is 30 + 118 = 148 years. If you add Kaydence's sister's age to the total age of the father, mother, and brother, you get 148 + 40 = 188 years. If everyone's age in the family is 200, then Kaydence's age is 200 - 188 = 12 years old. The answer is 12.
[Question]Half of Taylor's house guests like weak coffee and the other half like strong coffee in the morning. Taylor uses 1 tablespoon of coffee per cup of water to make it weak and he doubles that amount to make it strong. If he makes 12 cups of both weak and strong coffee, how many tablespoons of coffee will he need?
[Answer]He uses 1 tablespoon for weak coffee and doubles that for strong so the strong uses 1 * 2 = 2 tablespoons. For the weak coffee he uses 1 tablespoon per 1 cup of water and he needs to make 12 cups so he'll use 1 * 12 = 12 tablespoons. For the strong coffee he uses 2 tablespoons per 1 cup of water and he needs to make 12 cups so he'll use 2 * 12 = 24 tablespoons. All total he will use 12 tablespoons for the weak coffee and 24 tablespoons for the strong coffee for a total of 12 + 24 = 36 tablespoons. The answer is 36.
[Question]Ethan is reading a sci-fi book that has 360 pages. He read 40 pages on Saturday morning and another 10 pages at night. The next day he read twice the total pages as on Saturday. How many pages does he have left to read?
[Answer]
Ethan read a total of 40 pages + 10 pages = 50 pages on Saturday. On the next day, he read a total of 50 pages x 2 = 100 pages. The total number of pages that Ethan had read is 50 pages + 100 pages = 150 pages. Therefore, Ethan has 360 pages - 150 pages = 210 pages left to read. The answer is 210.
