Q: John's piggy bank contains quarters, dimes, and nickels. He has three more dimes than quarters and 6 fewer nickels than quarters. If he has 63 coins, how many quarters does John have?
A: Let x represent the number of quarters John has. Nickels: x - 6. Dimes: x + 3. Total:x + x - 6 + x + 3 = 63. 3x - 3 = 63. 3x = 66. x = 22 quarters. The answer is 22.

Q: A bird is building a nest from twigs. The bird has put twelve twigs together already to make a circle. For each twig it placed into the circle, it wants to weave in six more twigs to fill out the nest. It knows a tree that has dropped a third of the twigs it needs. How many twigs will the bird still need to find to finish its nest?
A: The bird wants 12 * 6 = 72 twigs to add to the nest. It knows a tree that has dropped 72 * 1 / 3 = 24 twigs. Thus, the bird will still need 72 - 24 = 48 twigs to finish the nest. The answer is 48.

Q: There are 40 Judges in the state of Rhode Island. 10 percent of Judges are under 30 years old. 60 percent of Judges are 30-50 years old. The rest of the Judges are over 50 years old. How many Judges are over 50 years old?
A:
Under 30: 40(.10) = 4. 30 - 50 years old:40(.60) = 24. Over 50:40 - 4 - 24 = 12 Judges. The answer is 12.
