Q: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
A: Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones. The answer is 111.

Q: Sol sells candy bars to raise money for her softball team. On the first day, she sells ten candy bars and sells four more candy bars than she sold the previous day each day afterward. If she sells six days a week and each candy bar costs 10 cents, how much will she earn in a week in dollars?
A: Sol will sell 10 + 4 = 14 candies on the second day. She will sell 14 + 4 = 18 candies on the third day. She will sell 18 + 4 = 22 candies on the fourth day. She will sell 22 + 4 = 26 candies on the fifth day. She will sell 26 + 4 = 30 candies on the sixth day. She will sell a total of 10 + 14 + 18 + 22 + 26 + 30 = 120 candies in a week. Hence, she will earn 120 x 10 = 1200 cents. Since 1 dollar is equal to 100 cents, then Sol will earn 1200 / 100 = $12. The answer is 12.

Q: Chance boarded a plane departing from London to New York at 6:00 a.m. ET on Monday. He arrived in New York 18 hours later. If he took another plane flying to Cape town the day he arrived in New York and arrived in Cape town at 10:00 a.m ET on Tuesday, calculate the number of hours his flight took from New York to cape town.
A:
Eighteen hours later, after departing from London, Chance arrived in New York at 6:00 + 18 hours = 00:00 on Tuesday. If he arrived in cape town at 10:00 p.m. on Tuesday, his flight took 10:00 - 00:00 = 10 hours. The answer is 10.
