[Question]Half of all the people in Nantucket will attend a planned meeting for a bowl game. There are 300 people in Nantucket, and the number of males going to the meeting is twice the number of females. How many females are going to the meeting?
[Answer]If half of the people in Nantucket are going to the planned meeting, then there are 1 / 2 * 300 = 150 people going to the meeting. If the number of males going to the meeting is twice the number of females, we'll assume the number of females is x and the number of males is 2x. We know that x + 2x = 150. Adding like terms produces 3x = 150. After dividing both sides by 3, we have x = 150 / 3 = 50. The number of females attending the meeting is x = 50. The answer is 50.
Q: A school is buying virus protection software to cover 50 devices. One software package costs $40 and covers up to 5 devices. The other software package costs $60 and covers up to 10 devices. How much money, in dollars, can the school save by buying the $60 software package instead of the $40 software package?
A: There are 50 / 5 = 10 sets of 5 devices in the school. So the school will pay a total of $40 x 10 = $400 for the $40 software package. There are 50 / 10 = 5 sets of 10 devices in the school. So the school will pay a total of $60 x 5 = $300 for the $60 software package. Thus, the school can save $400 - $100 = $300 from buying the $60 software instead of the $40 software package. The answer is 100.
Question: Mandy is ten years older than Jackson. Adele is 3/4 as old as Jackson. What's the total of their ages 10 years from now If Jackson is 20 years old now?
Answer: In ten years, Jackson will be 20 + 10 = 30 years old. If Jackson is 20 now, Mandy is 20 + 10 = 30 years old. Ten years from now, Mandy will be 30 + 10 = 40 years old. The combined age of Jackson and Mandy ten years from now is 30 + 40 = 70 years. Adele is 3 / 4 times as old as Jackson, meaning she is 3 / 4 * 20 = 15 years old. Adele's age will be 10 + 15 = 25 years old ten years from now. Altogether, Mandy, Jackson, and Adele will have a total of 25 + 70 = 95 years. The answer is 95.
[Question]Lily is going abroad on vacation with her family. Each of her 4 siblings is bringing 2 suitcases, and her parents are bringing 3 suitcases. Lily decides that there is already too much luggage and she won't be bringing any. How many suitcases is the entire family bringing on vacation?

Q: Anna is reading a 31-chapter textbook, but she skips all the chapters that are divisible by 3. If it takes her 20 minutes to read each chapter, how many hours does she spend reading total?
A: First divide 32 by 3, ignoring the remainder, to find how many chapters in the book are divisible by 3: 31 / 3 = 10.33..., which means 10 chapters are divisible by 3. Then subtract that number from the total number of chapters to find how many chapters she reads: 31 chapters - 10 chapters = 21 chapters. Then multiply the number chapters by the time to read each chapter to find the total time she spends reading: 21 chapters * 20 minutes / chapter = 420 minutes. Then divide that time by the number of minutes per movie to find the total time spent reading in hours: 420 minutes / 60 minutes / hour = 7 hours. The answer is 7.
