Q: At a gathering, it was reported that 26 people took wine, 22 people took soda, and 17 people took both drinks. If each person could have taken one or more drinks regardless of what was reported, how many people altogether were at the gathering?
A: The number of people who took only wine is the difference between the number of people who took wine and those who took wine and soda which is 26 - 17 = 9 people. In the same manner, the number of people who took only soda is 22 - 17 = 5 people. Therefore the total number present is the sum of those who took wine only, those who took soda only and those who took both which is 9 + 5 + 17 = 31 people. The answer is 31.
Question: John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?
Answer: The cost of the hearing aids is $2500 * 2 = $5000. So insurance covers $5000 * .8 = $4000. That means it cost him $5000 - $4000 = $1000. The answer is 1000.

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: 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.
Question: Lagoon island is populated by alligators. Half the alligators are male. The rest are female. Among the females, 40% are juveniles. There are 15 adult females. How many male alligators are there?
Answer:
60% of female alligators are adults because 100 - 40 = 60. There are 25 female alligators because 15 / .6 = 25. There are 50 alligators in total because 25 / .5 = 50. There are 25 male alligators because 50 / 2 = 25. The answer is 25.
