Q: A classroom of 15 students turned in essays on Friday morning. The first 5 students each turned in essays with 2 pages. The next 5 students each turned in essays with 3 pages. The last 5 students each turned in essays with 1 page. What is the average page count per essay for the 15 students?
A: The first 5 students turned in a total of 2 * 5 = 10 pages. The next 5 students turned in a total of 3 * 5 = 15 pages. The last 5 students turned in a total of 1 * 5 = 5 pages. In total there are 30 pages turned in by the students. For the 15 students, the average page count per essay is 30 / 15 = 2 pages. The answer is 2.
Question: James makes potatoes for a group. Each person eats 1.5 pounds of potatoes. He makes potatoes for 40 people. A 20-pound bag of potatoes costs $5. How much does it cost?
Answer: He needs 1.5 * 40 = 60 pounds of potatoes. So he needs to buy 60 / 20 = 3 bags of potatoes. So it cost 3 * 5 = $15. The answer is 15.
[Question]In the spelling bee, Max has 5 points, Dulce has 3 points, and Val has twice the combined points of Max and Dulce. If they are on the same team and their opponents' team has a total of 40 points, how many points are their team behind?
[Answer]Max and Dulce's total combined points are 5 + 3 = 8. So, Val got 8 x 2 = 16 points. And the total points of their team is 8 + 16 = 24. Therefore, their team is 40 - 24 = 16 points behind. The answer is 16.
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: Eliana walked 200 steps for her morning exercise, did some press-ups, then added some 300 more steps to her count for the first day. The next day, she walked twice the number of steps she walked on the first day. And on the third day, Eliana walked an additional 100 steps. What's the total number of steps Eliana walked during these three days?
Answer: On the first day, she walks 200 + 300 = 500 steps. The next day she walks twice the steps, which is 2 * 500 = 1000. The total number of steps after the two days are 1000 + 500 = 1500. On the third day, she walks an additional 100 steps, bringing the three - day total to 1500 + 100 = 1600 steps. The answer is 1600.
Q: Mary brought 50 stickers to class. She gave 4 stickers to each of her 5 friends. She gave everyone else in class two stickers each. If she has 8 stickers left over, how many students are in the class, including Mary?
A:
She gave out 50 - 8 = 42 stickers in total. She gave 4 * 5 = 20 stickers to her friends. She gave out 42 - 20 = 22 stickers to the rest of the class. This means there are 22 / 2 = 11 other students in the class. There are a total of 1 + 5 + 11 = 17 students in the class. The answer is 17.
