user: Reasoning and answer: 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: 22

Question: 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?
Jill starts off spending 5 minutes on the phone, and the following day she spends double that 5 minutes for 5 * 2 = 10 minutes. The following day Jill spends double the previous day's total of 10 minutes on the phone, for 10 * 2 = 20 minutes. On the fourth day, Jill spends double the previous day's total of 20 minutes on the phone, for 20 * 2 = 40 minutes. On the fifth and final day, Jill spends double the previous day's total of 40 minutes on the phone, for 40 * 2 = 80 minutes. All told, Jill spends 5 + 10 + 20 + 40 + 80 = 155 minutes on the phone over 5 days.
The answer: 155
Reverse engineering the question: Jill spends time every day talking to her boyfriend on the phone. The first day of the week she spends 5 minutes on the phone with her boyfriend. Each of the following days she spends twice as much time talking on the phone as the day before. After the 5th day her parents take the phone away from her because she was on it too long. How much time did Jill spend talking to her boyfriend that week?
Reasoning and answer: Twice the number of hours in a typical earth day is 24 * 2 = 48 hours. Eight hours less than twice the number of hours in a typical earth day is 48 - 8 = 40 hours. If the distance between these two planets is 4,000 parsecs, then the average speed on this voyage was 4000 / 40 = 100 parsecs per hour.
The answer: 100

Question: During the most recent voyage of the Starship Conundrum, the spacecraft traveled from Planet X to Planet Y in eight hours less than twice the number of hours in a typical earth day. If the distance between these two planets is 4,000 parsecs, what was the average speed, in parsecs per hour, of the Starship Conundrum during this most recent voyage?
Max and Dulce's total combined points are 5 + 3 = 8. So, Val got 8 x 2 = 16 points. And the total points of their team is 8 + 16 = 24. Therefore, their team is 40 - 24 = 16 points behind.
The answer: 16
Reverse engineering the question: In the spelling bee, Max has 5 points, Dulce has 3 points, and Val has twice the combined points of Max and Dulce. If they are on the same team and their opponents' team has a total of 40 points, how many points are their team behind?
Reasoning and answer: First find the area of the first wall: 5 feet * 8 feet = 40 square feet. Then find the area of the second wall: 7 feet * 8 feet = 56 square feet. Then add the areas of the two walls to find the total area: 40 square feet + 56 square feet = 96 square feet. Then divide the number of square feet by the number of tiles per square foot to find the total number of tiles needed: 96 square feet * 4 tiles / square foot = 384 tiles. Then find the difference in cost per tile: $13 / tile - $11 / tile = $2 / tile. Then multiply the number of tiles by the cost difference per tile to find the total cost difference: $2 / tile * 384 tiles = $768.
The answer: 768

Question: Janet is considering two options to retile her bathroom. The turquoise tiles cost $13/tile and the purple tiles cost $11/tile. If Janet needs to tile two walls that measure 5 feet by 8 feet and 7 feet by 8 feet, and each square foot of wall takes 4 tiles, how much will Janet save by buying the purple tiles instead of the turquoise ones?
Reasoning and answer: Bogan served a total of 20 maggots. Bogan gave the beetles 10 maggots in the first feeding. Bogan gave the beetles 20 - 10 = 10 maggots in the second feeding.
The answer: 10

Question:

assistant: Bogan laid out 10 maggots for her pet beetle. The beetle only ate 1 and Bogan had to throw out the rest. Later that day, she tried feeding again and the beetle ate 3. If Bogan served 20 maggots in total, how many did she attempt to feed the beetle the second time?
