Question: Angelo and Melanie want to plan how many hours over the next week they should study together for their test next week. They have 2 chapters of their textbook to study and 4 worksheets to memorize. They figure out that they should dedicate 3 hours to each chapter of their textbook and 1.5 hours for each worksheet. If they plan to study no more than 4 hours each day, how many days should they plan to study total over the next week if they take a 10-minute break every hour, include 3 10-minute snack breaks each day, and 30 minutes for lunch each day?
Answer: Angelo and Melanie think they should dedicate 3 hours to each of the 2 chapters, 3 hours x 2 chapters = 6 hours total. For the worksheets they plan to dedicate 1.5 hours for each worksheet, 1.5 hours x 4 worksheets = 6 hours total. Angelo and Melanie need to start with planning 12 hours to study, at 4 hours a day, 12 / 4 = 3 days. However, they need to include time for breaks and lunch. Every hour they want to include a 10 - minute break, so 12 total hours x 10 minutes = 120 extra minutes for breaks. They also want to include 3 10 - minute snack breaks, 3 x 10 minutes = 30 minutes. And they want to include 30 minutes for lunch each day, so 120 minutes for breaks + 30 minutes for snack breaks + 30 minutes for lunch = 180 minutes, or 180 / 60 minutes per hour = 3 extra hours. So Angelo and Melanie want to plan 12 hours to study + 3 hours of breaks = 15 hours total. They want to study no more than 4 hours each day, 15 hours / 4 hours each day = 3.75. They will need to plan to study 4 days to allow for all the time they need. The answer is 4.
[Question]Harrison Elementary School is overcrowded with 1590 students, so 40% of the students are going to move to a new school. There are 3 grade levels, and each grade level needs one 20-person advanced class and the rest of the students divided evenly into 6 additional classes. How many students will there be in each normal class at the new school?
[Answer]First find how many students go to the new school: 1590 students * .4 = 636 students. Then divide that number by 3 to find how many students are at each grade level: 636 students / 3 grades = 212 students / grade. Then subtract the 20 students in the gifted class: 212 students - 20 students = 192 students. Then divide that number by 6 to find the number of students in each other class: 192 students / 6 classes = 32 students / class. The answer is 32.
Q: At the Mystic Aquarium, sharks are fed four buckets of fish each day. The dolphins are fed half as many buckets as the sharks while the other sea animals are fed five times as many buckets as the sharks. How many weeks will 546 buckets of fish last?
A: The dolphins are fed 4 / 2 = 2 buckets of fish each day. The sea animals are fed 4 x 5 = 20 buckets of fish each day. So, the Mystic Aquarium needs 4 + 2 + 20 = 26 buckets of fish each day. Thus in a week, it needs 26 x 7 = 182 buckets of fish. Therefore, 546 buckets of fish will last for 546 / 182 = 3 weeks. The answer is 3.
Question: Anna wears a size 2. Her friend Becky wears a size three times larger than Anna's. Ginger wears a size twice Becky's size minus 4. What size does Ginger wear?
Answer: First find what size Becky wears: 2 * 3 = 6. Then multiply that number by 2: 6 * 2 = 12. Then subtract 4 to find Ginger's size: 12 - 4 = 8. The answer is 8.
Q: Nina has two pairs of shoes. She bought one of them for $22, and the second one was 50% more expensive. How much did Nina pay for both pairs of shoes?
A:
The second pair of shoes was 50 / 100 * 22 = $11 more expensive. That means that the second pair's price was 22 + 11 = $33. So for both pairs of shoes, Nina paid 33 + 22 = $55. The answer is 55.
