Q: Taipei 101 in Taiwan is 1,673 feet tall with 101 floors. Suppose the first to 100th floors have height each equal to 16.5 feet, how high is the 101st floor?
A: The total height of the first to 100th floor is 100 x 16.5 = 1650 feet. Hence, the 101st floor is 1673 - 1650 = 23 feet high. The answer is 23.
Question: Trip wanted to watch the new action movie in theaters. An evening ticket cost $10 and a large popcorn & drink combo would cost him an additional $10. He noticed on their website, they had a special offer. From 12 noon to 3 pm, save 20% off tickets and 50% off any food combos. How much money could Trip save by going to the earlier movie?
Answer: An evening movie is $10 and the food combo would be $10 so 10 + 10 = $20. If he goes to an earlier movie, it's 20% off the normal ticket price of $10 so 10 * .20 = $2. If he goes to an earlier movie, it's 50% off the normal food price of $10 so 10 * .50 = $5. If he saves $2 for the ticket and $5 on food, then 2 + 5 = $7 saved. The answer is 7.

Q: David swims the 100-meter freestyle in 48 seconds. He swims the 100-meter backstroke 4 seconds slower than he swims the 100-meter freestyle, he swims the 100-meter butterfly 3 seconds slower than he swims the 100-meter backstroke, and he swims the 100-meter breaststroke 2 seconds slower than he swims the 100-meter butterfly. What is the combined length of time, in seconds, it would take for him to swim all four 100-meter events (the freestyle, the backstroke, the butterfly, and the breaststroke)?
A:
David swims the 100m backstroke at 48 + 4 = 52 seconds. He swims the 100m butterfly at 52 + 3 = 55 seconds. He swims the 100m breaststroke at 55 + 2 = 57 seconds. IN total, it would take David 48 + 52 + 55 + 57 = 212 seconds. The answer is 212.
