[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.
So the answer is 4.

[Question]: Haylee has 3 dozen guppies in her aquarium. Jose has half as many guppies as Haylee in his tank. Charliz has one-third of what Jose has in his tank. Nicolai has 4 times as many guppies as Charliz in his pond. How many guppies do the four friends have altogether?
[Answer]: Haylee has 3 x 12 = 36 guppies. Jose has 36 / 2 = 18 guppies. Charliz has 18 / 3 = 6 guppies. Nicolai has 6 x 4 = 24 guppies. Altogether, the four friends have 36 + 18 + 6 + 24 = 84 guppies.
So the answer is 84.

[Question]: Bella, Monica, and Rachel are friends who like jewelry. Bella has 10 earrings, which is 25% of Monica's earrings, and Monica has twice as many earrings as Rachel. How many earrings do all of the friends have?
[Answer]:
Bellas has 100% / 25% = 4 times less earrings than Monica. This means that Monica has 10 * 4 = 40 earrings. Rachel has two times fewer earrings than Monica, which means 40 / 2 = 20 earrings. So all three friends, have a total of 10 + 40 + 20 = 70 earrings.
So the answer is 70.
