The amount in taxes Dorothy needs to pay is 18 / 100 * 60000 = $10800. So she is going to be left with 60000 - 10800 = $49200.
The answer: 49200
Reverse engineering the question: Dorothy earns $60000 a year from her work. She needs to pay 18% of this amount in taxes. How much money will she have left after she pays the taxes?


Reasoning and answer: The total cost of the hip - hop classes is 2 * $10 = $20. The total cost of the ballet classes is 2 * $12 = $24. The total cost of the jazz class is 1 * $8 = $8. The total cost of all of Lucia’s dance classes in one week is $20 + $24 + $8 = $52.
The answer: 52
What was the question?
Question: Lucia is a dancer. She takes 2 hip-hop classes a week, 2 ballet classes a week, and 1 jazz class a week. One hip-hop class costs $10. One ballet class costs $12, and one jazz class costs $8. What is the total cost of Lucia’s dance classes in one week?


Let S be the number of people on the first hundred years’ ship. The second hundred years’ ship had twice as many as the first, so it had 2S people. The third hundred years’ ship had twice as many as the second, so it had 2 * 2S = 4S people. All the ships had S + 2S + 4S = 7S = 847 people. Thus, the ship that the monster ate in the first hundred years had S = 847 / 7 = 121 people on it.
The answer: 121
Reverse engineering the question: A deep-sea monster rises from the waters once every hundred years to feast on a ship and sate its hunger. Over three hundred years, it has consumed 847 people. Ships have been built larger over time, so each new ship has twice as many people as the last ship. How many people were on the ship the monster ate in the first hundred years?


Reasoning and answer: Herbert is 24 - 10 = 14 years old now. Thus, Herbert will be 14 + 1 = 15 years old next year.
The answer: 15
What was the question?
Question: Herbert is 10 years younger than Kris. If Kris is 24 years old now, how old will Herbert be next year?


Sansa earns $5 x 3 = $15 every day by selling three 8 - inch portraits. The price of the 16 - inch portrait is $5 x 2 = $10 each. So, she earns $10 x 5 = $50 every day by selling five 16 - inch portraits. Her total earnings is $50 + $15 = $65 every day. Therefore, the total amount she earns after 3 days is $65 x 3 = $195.
The answer: 195
Reverse engineering the question: Sansa is a famous artist, she can draw a portrait and sell it according to its size. She sells an 8-inch portrait for $5, and a 16-inch portrait for twice the price of the 8-inch portrait. If she sells three 8-inch portraits and five 16-inch portraits per day, how many does she earns every 3 days?


In round one, Jeff completed 16 - 1 = 15. In round two, Jeff completed 16 - 3 = 13. In round three, Jeff completed 16 + 4 = 20. In round four, Jeff completed 16 / 2 = 8. Jeff completed 15 + 13 + 20 + 8 = 56 skips in total. Jeff skipped an average of 56 / 4 = 14 skips per round.
The answer: 14
Reverse engineering the question:
Sam and Jeff had a skipping competition at recess. The competition was split into four rounds. Sam completed 1 more skip than Jeff in the first round. Jeff skipped 3 fewer times than Sam in the second round. Jeff skipped 4 more times than Sam in the third round. Jeff got tired and only completed half the number of skips as Sam in the last round. If Sam skipped 16 times in each round, what is the average number of skips per round completed by Jeff?
