Q: Rita is reading a five-chapter book with 95 pages. Each chapter has three pages more than the previous one. How many pages does the first chapter have?
A: Let P be the number of pages in the first chapter. The second chapter has P + 3 pages. The third chapter has P + 3 + 3 = P + 6 pages. The fourth chapter has P + 6 + 3 = P + 9 pages. The fifth chapter has P + 9 + 3 = P + 12 pages. The whole book has P + 3 + P + 6 + P + 9 + P + 12 = 5P + 30 = 95 pages. Thus, without the 30 extra pages from additional chapters, 5P = 95 - 30 = 65 pages. Therefore, the first chapter had P = 65 / 5 = 13 pages. The answer is 13.

Q: At a UFO convention, there are 120 conference attendees. If there are 4 more male attendees than female attendees, how many male attendees are there?
A: Let's assume the number of female attendees is x. The number of male attendees is x + 4. The sum of male attendees and female attendees is x + x + 4 = 120. 2x + 4 = 120. 2x = 116. The number of female attendees is x = 116 / 2 = 58. The number of male attendees is 58 + 4 = 62. The answer is 62.

Q: Marco uses a fifth of an ounce of dry tea leaves to brew his morning cup of tea each day. He buys tea leaves in boxes of 28 ounces. How many weeks of daily tea does Marco get from a box?
A:
Marco gets 28 / 1 / 5 = 28 * 5 = 140 cups of tea from a box. At 7 days a week, Marco gets 140 / 7 = 20 weeks of daily tea from a box. The answer is 20.
