First figure out how many miles over the speed limit Mark was going: 75 mph - 30 mph = 45 mph. Now figure out how much the per - mile fine is: $2 / mph * 45 mph = $90. Now add that amount to the base fine: $90 + $50 = $140. Now double that amount for being in a school zone: $140 * 2 = $280. Now figure out how much Mark owes his lawyer: $80 / hour * 3 hours = $240. Now add the court costs, lawyer fees and fine: $240 + $300 + $280 = $820.
The answer: 820
Reverse engineering the question: Mark was caught speeding and the judge wants to make an example out of him. The base fine for speeding is $50 but additional penalties apply in this case. The fine is increased by $2 for every mile per hour Mark was going over the speed limit. He was going 75 miles per hour in a 30 mile per hour zone. The fine is also doubled because he was in a school zone. Finally, the judge makes Mark pay $300 in court costs and he also has to pay his lawyer $80/hour for three hours of work. How much does Mark owe for this speeding ticket?


Reasoning and answer: In one week, he bakes 3 * 12 = 36 apple pies. In one week, he bakes 2 * 12 = 24 cherry pies. He bakes 36 - 24 = 12 more apple pies.
The answer: 12
What was the question?
Question: Steve has decided to become a baker. On Mondays, Wednesdays and Fridays, he bakes apple pies. On Tuesdays and Thursdays, he bakes cherry pies. If he bakes 12 pies per day, how many more apple pies does he bake than cherry pies in one week?


The height is 20 feet taller than 500 feet, or 500 + 20 = 520 feet. The structure is 234 feet wider than it is tall, or a width of 520 + 234 = 754 feet wide. Therefore, the sum of the height and width of the Great Pyramid of Giza is 520 + 754 = 1274 feet.
The answer: 1274
Reverse engineering the question: The Great Pyramid of Giza was the tallest man-made structure on earth for almost 4000 years. It is 20 feet taller than 500 feet, and 234 feet wider than it is tall. What is the sum of the height and width of the Great Pyramid of Giza in feet?


Reasoning and answer: Deduct the amount saved from the total cost of the set. $65 - $35 = $30. Deduct the amount of money Gabby received from her mom. $30 - $20 = $10.
The answer: 10
What was the question?
Question: Gabby is saving money to buy a new makeup set. The makeup set costs $65 and she already has $35. Gabby’s mom gives her an additional $20. How much money does Gabby need to buy the set?


The total number of apples delivered was: 180 apples x 12 crates = 2160 apples. So, the number of remaining apples after throwing away the rotten ones was: 2160 apples – 160 apples = 2000 apples. And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples / box = 100 boxes of apples.
The answer: 100
Reverse engineering the question: There were 180 apples in each crate. 12 such crates of apples were delivered to a factory. 160 apples were rotten and had to be thrown away. The remaining apples were packed into boxes of 20 apples each. How many boxes of apples were there?


Tank's total number of eggs in the second round was 60 / 2 = 30 since Emma gathered twice as many eggs as Tank in their second round of egg hunt. The total number of eggs that Emma and Tank gathered in the second round was 60 + 30 = 90. Tank's total number of eggs in the second round was 20 less than the number she had gathered in the first round, meaning she had gathered 30 + 20 = 50 eggs in the first round of egg hunt. Tank gathered 10 more Easter eggs than Emma in their first round of egg hunt, meaning Emma collected 50 - 10 = 40 eggs. The total number of eggs Emma and Tank collected in the first round was 40 + 50 = 90. In the two rounds, Emma and Tank gathered 90 + 90 = 180 eggs. If the total number of eggs in the pile they were collecting with 6 other people was 400 eggs, the six other people gathered 400 - 180 = 220 eggs.
The answer: 220
Reverse engineering the question:
In April, Tank gathered 10 more Easter eggs than Emma in their first round of egg hunt. However, Emma gathered twice as many eggs as Tank in their second round of egg hunt, while Tank's total number of eggs in the second round was 20 less than the number she had gathered in the first round. If the total number of eggs in the pile they were collecting with 6 other people was 400 eggs, and Emma gathered 60 eggs in the second egg hunt round, find the number of eggs that the 6 other egg hunters collected?
