Question: Bob, Tom, Sally, and Jerry had dinner at their favorite pizzeria. They decide to share 2 pizzas. Bob ate half of a pizza on his own. Tom ate one-third of a pizza. Sally wasn't very hungry and only ate one-sixth of a pizza, and Jerry ate a quarter of a pizza. If each pizza is cut into 12 slices, how many slices were left over?
Answer: Each pizza is 12 slices. Bob at 12 slices / 2 = 6 slices. Tom ate one third, or 12 slices / 3 = 4 slices. Sally ate one sixth, or 12 slices / 6 = 2 slices. Jerry ate one quarter, or 12 slices / 4 = 3 slices. In total, they ate 6 slices + 4 slices + 2 slices + 3 slices = 15 slices. So they were left with 12 slices per pizza * 2 pizzas - 15 slices = 24 slices - 15 slices = 9 slices. The answer is 9.

Q: Each week Carina puts 20 more seashells in a jar than she did the week before. If there are 50 seashells in the jar this week, how many will there be in a month?
A: In one week there will be 50 + 20 = 70 seashells. In two weeks there will be 70 + 20 = 90 seashells. In three weeks there will be 90 + 20 = 110 seashells. In four weeks there will be 110 + 20 = 130 seashells. The answer is 130.
Question: A coal-powered train is traveling towards a faraway city when the conductor realizes that he forgot to restock the train's coal supply at the last station. The train is traveling on a one-way track, so the conductor has no other option but to continue moving forward towards the city. The train can travel 5 miles for every 2 pounds of coal that it consumes. If the train has 160 pounds of coal remaining, how far can the train travel before it runs out of fuel?
Answer: The train travels 5 miles per every 2 pounds, or 5 / 2 = 2.5 miles per pound of coal. Therefore, the 160 pounds of coal that remain are enough for the train to travel 160 * 2.5 = 400 miles. The answer is 400.
[Question]Allie, Rob, and Allyn each bought a bowl of grapes. Allie's bowl contained two more grapes than Rob's bowl. Allyn's bowl contained four more grapes than Allie's bowl. If Rob's bowl contained 25 grapes, what is the total combined number of grapes in all three bowls?
[Answer]If Allie's bowl contained two more grapes than Rob's bowl, there were 25 + 2 = 27 grapes in Allie's bowl. If Allyn's bowl contained four more grapes than Allie's bowl, there were 27 + 4 = 31 grapes in Allyn's bowl. The total combined number of grapes in all three bowls is 25 + 27 + 31 = 83 grapes. The answer is 83.
[Question]Bonny just bought her 13th pair of shoes, which is 5 less than twice as many pairs of shoes as Becky owns. Bobby has 3 times as many pairs of shoes as Becky has. How many shoes does Bobby have?
[Answer]
Let x be the number of pairs of shoes that Becky owns. Since 13 pairs is 5 less than twice as many pairs as Becky owns, then the relationship is 2x - 5 = 13. Adding 5 to each side of the equation, we get 2x = 18. Solving for x, we get x = 9. Since Bobby has 3 times as many pairs of shoes as Becky has, then Becky has 3 * 9 = 27 pairs of shoes. The answer is 27.
