Answer this question: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?
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.
The answer is 23.

Answer this question: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?
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.
The answer is 18.

Answer this question: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?

The answer is 50.
