Question and rationale: The question is: Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
Step-by-step reasoning process: Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos.

Question and rationale: The question is: 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?
Step-by-step reasoning process: 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.

Question and rationale: The question is: A group of six friends planned to buy a car. The cost of the car is $1700 and they plan to share the cost equally. They had a car wash to help raise funds, which would be taken out of the total cost. The remaining cost would be split between the six friends. At the car wash, they earn $500. However, Brad decided not to join in the purchase of the car. How much more does each friend have to pay now that Brad isn't participating?
Step-by-step reasoning process: Start by finding the total that is left, $1700 car price - $500 earned at car wash = $1200 remaining. So the six friends should pay $1200 / 6 people = $200 each. Since Brad is not joining, then the 5 friends have to split Brad's share which is $200 / 5 = $40 each.
