Mikaela spent 35 + 5 = 40 hours in the second month. So, she tutored a total of 35 + 40 = 75 hours for the first two months. Thus, her total earning was 75 x $10 = $750. And, her total expenses was 4 / 5 x $750 = $600. Therefore, she saved an amount of $750 - $600 = $150.
The answer: 150
Reverse engineering the question: Mikaela earns $10 an hour tutoring. For the first month, she tutored for 35 hours and in the second month, she tutored 5 hours more than the first month. She spent 4/5 of her total earnings on her personal needs and saved the rest of the money. How much did she save?


Reasoning and answer: The total amount of children that went on both days is 7 + 4 = 11. The cost of the children's tickets is 11 × $3 = $33. The total amount of adults that went on both days is 5 + 2 = 7. The cost of the adults' tickets is 7 × $4 = $28. The zoo made $33 + $28 = $61 in total.
The answer: 61
What was the question?
Question: On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?


In total, Rick is still owed 400 - 285 = $115. Derek owes half as much as Amy, so he owes $30 / 2 = $15. This means that Sally and Carl owe a combined total of $115 - $30 – $15 = $70. As they owe equal amounts, they therefore owe $70 / 2 = $35 each.
The answer: 35
Reverse engineering the question: Rick held a fundraiser and is figuring out who still owes money. He marked on a sheet how much everyone has promised to contribute, but he forgot to note how much some people had actually paid. Altogether, everyone has promised to contribute $400, and Rick has actually received $285. Sally, Amy, Derek, and Carl all still owe money. Sally and Carl both owe equal amounts, Amy owes $30, and Derek owes half as much as Amy. How much, in dollars, do Sally and Carl each owe?


Reasoning and answer: Let x be the weight of the fish that Peter caught. Then Ali and Joey caught 2 * x and x + 1 kg of fish, respectively. So, x + 2 * x + x + 1 = 25. So, 4 * x = 25 - 1 = 24. So, x = 6. Therefore, Ali caught 2 * x = 2 * 6 = 12 kg of fish.
The answer: 12
What was the question?
Question: Ali, Peter, and Joey were fishing. The fish Ali caught weighed, in sum, twice as much as the fish that Peter caught. Joey caught 1 kg more fish than Peter. Together the three of them caught 25 kg of fish. How many kilograms did Ali catch?


There are 12 months in 1 year and his loan is for 5 years so that's 12 * 5 = 60 months. His monthly payment is $150.00 and he pays this for 60 months so his loan for the tractor was 150 * 60 = $9,000.00.
The answer: 9000
Reverse engineering the question: Gunther just financed a John Deere tractor through the dealership. If his monthly payment is $150.00 a month, for 5 years, with no interest, how much did he finance the tractor for?


Earl was on the 1 + 5 = 6th floor after going up 5 floors. When he went down 2 floors, he was on the 6 - 2 = 4th floor. Since he went up 7 floors, he was then on the 4 + 7 = 11th floor. Since he is 9 floors away from the top of the building, therefore the building has 11 + 9 = 20 floors.
The answer: 20
Reverse engineering the question:
Earl started delivering newspapers on the first floor of a condominium building. He then went up 5 floors then went down 2 floors. He again went up 7 floors and found that he is 9 floors away from the top of the building. How many floors does the building have?
