Q: Hallie borrows a book from the library. She reads the entire book in four days. She read 63 pages the first day. On the second day, she read twice the number of pages that she'd read on day one. On the third day, she read 10 mores pages than she read on day two. If the book is 354 pages long, how many pages did she read on the fourth day?
A: On day two, she read 63 * 2 = 126 pages. On day three, she read 126 + 10 = 136 pages. On day four, she read 354 - 63 - 126 - 136 = 29 pages to finish the book. The answer is 29.
Question: Chandra is going on a monster hunt. After a big storm, there have been lost monsters all around the castle grounds for the last 5 days. Chandra wants to rope them all up and return them to the swamps where they will be the most comfortable. On the first day she saw 2 monsters near the castle walls. Every day after that she saw double the amount as the day before. After 5 days how many monsters does she need to lead back to the swamps?
Answer: On the first day Chandra saw 2 monsters and on day 2 she saw twice that amount, 2 x 2 = 4 monsters seen on day 2. On day 3 she saw double that amount of monsters, 4 x 2 = 8. On day 4 she saw double that amount of monsters, 8 x 2 = 16. On day 5 she saw double that amount of monsters, 16 x 2 = 32. Altogether Chandra saw 2 + 4 + 8 + 16 + 32 lost monsters = 62 total lost monsters that Chandra needs to lead back to the swamps. The answer is 62.
[Question]Daria consumes 2.5 times the amount of pizza that Don does. If Don eats 80 pizzas, how many pizzas do they both eat altogether?
[Answer]Since Daria consumes two and a half times the amount of pizza that Don does, if Don eats 80 pizzas, Daria eats 2.5 * 80 = 200 pizzas. Together, they eat 200 + 80 = 280 pizzas. The answer is 280.
Q: Anna wants to grow some lettuce in the garden and would like to grow enough to have at least 12 large salads. She estimates that, despite her best efforts, half of the lettuce will be lost to insects and rabbits. Each lettuce plant is estimated to provide 3 large salads. How many lettuce plants should Anna grow in the garden?
A: The total number of plants needed for 12 dinner salads (without loss to insects or rabbits) is 12 / 3 salads from each lettuce plant = 4 lettuce plants. Since Anna expects to lose half of her plants to insects and rabbits, so we need to plant twice as many plants or 4 * 2 = 8 lettuce plants. The answer is 8.
Question: Jerry is sweeping up pieces of broken glass in the parking lot. He sweeps up 20 amber pieces, 35 green pieces, and some clear pieces. If the green pieces are 25% of the total glass he sweeps up, how many pieces were clear?
Answer: First find the total number of glass pieces Jerry sweeps up: 35 green pieces / .25 = 140 pieces. Then subtract the number of pieces of other colors: 140 pieces - 20 pieces - 35 pieces = 85 pieces. The answer is 85.
Q: Rhonda, Sally, and Diane are members of their school's track team. The three of them run the 600-meter relay race together. Rhonda runs the first 200 meters of the race, Sally runs the second 200 meters of the race, and Diane runs the final 200 meters of the race. Rhonda can run 200 meters in 24 seconds. Sally takes two seconds longer to run the same distance, while Diane can run 200 meters three seconds faster than Rhonda. How many seconds does it take for the three of them to run the 600-meter relay race?
A:
Sally takes 24 + 2 = 26 seconds. Diane takes 24 - 3 = 21 seconds. Thus, the three take 24 + 26 + 21 = 71 seconds to run the 600 - meter relay race. The answer is 71.
