[Question]There are 3 ducks in a pond and they all eat some pieces of bread thrown in the water. One duck eats half of all the pieces of bread. Another duck eats only 13 pieces of the bread and the last duck eats 7 pieces of bread. There are 30 pieces of bread left in the water, how many total pieces of bread were thrown in the pond?
[Answer]There are 30 + 7 + 13 = 50 pieces of bread after the first duck ate. The first duck ate half of all bread so 50 * 2 = 100 pieces of bread were thrown in the pond. The answer is 100.
Q: Rich likes to take long walks through town. First he walks 20 feet from his house to the sidewalk. Then he walks 200 feet down the sidewalk to the end of the road. Then he makes a left and walks double his total distance so far until he reaches the next intersection. Then he walks half the total distance up to this point again to the end of his route, before turning around and walking the same path all the way back home. How many feet did Rich walk?
A: Rich walks 20 + 200 = 220 feet to get to the end of the road. He then walks double that distance, 220 * 2 = 440 feet to the next intersection. This makes a total of 220 + 440 = 660 feet. He then walks half that distance, 660 / 2 = 330 feet to get to the end of his route. This makes a total of 660 + 330 = 990 feet so far. He then walks that same distance back, for a total of 990 * 2 = 1980 feet in total. The answer is 1980.
Question: There are 80 passengers on the airplane where the number of men and women is equal. The rest of the passengers are children. How many children are on the airplane if there are 30 men?
Answer: Since the number of men and women is equal, then there are a total of 30 + 30 = 60 men and women. Thus, 80 - 60 = 20 children are on the airplane. The answer is 20.

Q: James gets 3 parking tickets. The first 2 cost $150 each and the third cost 1/3 as much as one of these. His roommate agrees to pay half the cost. How much money does he have left if he had $500 in the bank?
A: The third ticket cost $150 / 3 = $50. So the tickets cost $150 * 2 + $50 = $350. That means he paid $350 / 2 = $175. So he had $500 - $175 = $325 left over. The answer is 325.
