[Question]James has 20 years of experience. 8 years ago John had twice as much experience as James. Mike started when John had 16 years of experience. What is their combined experience?
[Answer]8 years ago James had 20 - 8 = 12 years. So 8 years ago John had 12 * 2 = 24 years experience. That means John has 24 + 8 = 32 years experience. So Mike has 32 - 16 = 16 years of experience. So together they have 20 + 32 + 16 = 68 years experience. The answer is 68.

A: Full Equipment Price for one player: $25 + $15.20 + $6.80 = $47. Prices for full equipment for 16 people: 16 players x $47 / player = $752. The answer is 752.
Question: Daisy's Flower Shop sold 45 daisies on its first day. On their second day, they sold 20 more flowers than they did on their first day. On the third day, they sold 10 less than twice the flowers that were sold than on the second day. If the flower shop sold a total of 350 daisies for 4 days, how many daisies were sold on the 4th day?
Answer: The flower shop sold 45 + 20 = 65 daisies on the second day. Twice the number of flowers on the second day is 65 x 2 = 130. So, the flower shop sold 130 - 10 = 120 daisies on the third day. The total daisies sold for 3 days was 45 + 65 + 120 = 230. Therefore, 350 - 230 = 120 daisies were sold on the 4th day. The answer is 120.
[Question]Alice had 10 dozens of watermelons. She sold 40% of it yesterday and 1/4 of the remaining today, How many watermelons are left to be sold tomorrow?
[Answer]Ten dozens of watermelons are equal to 10 x 12 = 120 watermelons. Yesterday, Alice sold 120 x 40 / 100 = 48 watermelons. So, there are only 120 - 48 = 72 watermelons left for today. Today, Alice sold 72 x 1 / 4 = 18 watermelons. Hence, 72 - 18 = 54 watermelons are left to be sold tomorrow. The answer is 54.
Q: Peter and Andrew like to run in the morning. Peter runs 3 miles more than Andrew's 2 miles. After 5 days, how many miles have they both run?
A: Peter runs 3 miles more than Andrew's 2 miles, so he runs 3 + 2 = 5 miles. Peter runs 5 miles a day and Andrew runs 2 miles so they run 5 + 2 = 7 miles a day. If they run 7 miles a day then over a course of 5 days they run 7 * 5 = 35 miles. The answer is 35.
Question: Eastern rattlesnakes have 6 segments in their tails, while Western rattlesnakes have 8 segments. What is the percentage difference in their tail size, expressed as a percentage of the Western rattlesnake's tail size?
Answer:
First find the difference in size between the two kinds of snake tail: 8 segments - 6 segments = 2 segments. Then divide that amount by the size of the Western rattlesnake's tail and multiply by 100% to express the answer as a percentage: 2 segments / 8 segments * 100% = 25%. The answer is 25.
