Q: The Chrysler Building has 11 more floors than the Leeward Center. Together they have a total of 35 floors. How many floors does the Chrysler Building have?
A: 23
Step-by-step reasoning process: Let L = Leeward Center. Chrysler = L + 11. L + L + 11 = 35. 2L + 11 = 35. 2L = 24. Leeward = 12 floors. Chrysler = 12 + 11 = 23 floors. The Chrysler Building has 23 floors.


Q: Sami finds 3 spiders in the playground. Hunter sees 12 ants climbing the wall. Ming discovers 8 ladybugs in the sandbox, and watches 2 of them fly away. How many insects are remaining in the playground?
A: 21
Step-by-step reasoning process: The children find 3 + 12 + 8 = 23 insects. After the ladybugs fly away, there are 23 - 2 = 21 insects.


Q: Mark has two pets, a hare that runs 10 feet/second and a turtle that crawls 1 foot/second. If they're going to run a 20 foot-race, how much of a head start (in seconds) does the turtle need to finish in a tie?
A: 18
Step-by-step reasoning process: We can find how long the hare spends running by dividing the distance of the race by the hare's speed: 20 feet / 10 feet / second = 2 seconds. We can do the same for the turtle: 20 feet / 1 foot / second = 20 seconds. Finally, subtract the hare's run time from the turtle's run time to find the length of the head start the turtle needs: 20 seconds - 2 seconds = 18 seconds.


Q: Georgia has 25 pieces of stationery while Lorene has three times as many pieces of stationery as Georgia. How many fewer pieces of stationery does Georgia have than Lorene?
A: 50
Step-by-step reasoning process: Lorene has 25 x 3 = 75 pieces of stationery. Thus, Georgia has 75 - 25 = 50 fewer pieces of stationery than Lorene.
