Q: Rick took off on a road trip for the summer. He traveled to the first destination on his trip, and then from there, he traveled twice the distance to this second destination. The third point on his trip was 40 miles away, which was half the distance he traveled from the beginning to his first destination. The final destination took twice the amount of driving of all the other legs put together. How many miles in total did he travel across all the legs of the trip?
A: If the third leg of Rick's trip was half the distance of the first leg, was 40 miles, this means the first leg was 40 * 2 = 80 miles long. If the second leg of the trip was twice the distance of the first leg, that means it was 80 * 2 = 160 miles long. If the fourth leg was equal in distance to the total amount traveled across the first 3 legs, that means it was equal to 40 + 80 + 160 = 280 miles long. This means in total Rick traveled 280 + 280 = 560 miles. The answer is 560.

Q: Rachel weighs 75 pounds, 6 pounds less than Jimmy and 15 pounds more than Adam. What is the average weight of the three people, in pounds?
A: Jimmy weighs 75 + 6 = 81 pounds. Adam's weight is 75 - 15 = 60 pounds. In total, the three weigh 75 + 81 + 60 = 216 pounds. The average weight of the three is 216 / 3 = 72 pounds. The answer is 72.

Q: Dolly wants to ride the Ferris wheel twice, the roller coaster three times, and the log ride seven times. The Ferris wheel costs 2 tickets, the roller coaster costs 5 tickets and the log ride costs 1 ticket. Dolly has 20 tickets. How many more tickets should Dolly buy?
A:
It costs 2 rides x 2 tickets / ride = 4 tickets to ride the Ferris wheel twice. It costs 3 rides x 5 tickets / ride = 15 tickets to ride the roller coaster three times. It costs 7 rides x 1 ticket / ride = 7 tickets to ride the roller coaster seven times. In total Dolly needs 4 tickets + 15 tickets + 7 tickets = 26 tickets. Dolly needs to buy 26 tickets - 20 tickets = 6 more tickets. The answer is 6.
