Reasoning and answer: They earned $11 x 5 = $55 for the phone repairs. They earned $15 x 2 = $30 for the laptop repairs. They also earned $18 x 2 = $36 for computer repairs. Therefore, Care and Rick earned $55 + $30 + $36 = $121 for the week.
The answer: 121
What was the question?
Question: Care and Rick have a repair shop. Each repair is priced differently: phone repair costs $11, laptop repair costs $15 and computer repair costs $18. If they perform 5 phone repairs, 2 laptop repairs, and 2 computer repairs for this week, how much did they earn for the week?
Julia has 1 / 3 * 6 = 2 video games. Theresa has 3 * 2 + 5 = 11 video games.
The answer: 11
Reverse engineering the question: Theresa has 5 more than thrice as many video games as Julia. Julia has a third as many video games as Tory. If Tory has 6 video games, how many video games does Theresa have?
Reasoning and answer: The sum of the ratios representing the amount of money the three has is 4 + 5 + 6 = 15. If the total amount of money they have is $75, the amount of money Cara has represented by the fraction 4 / 15 is 4 / 15 * $75 = $20. Similarly, the amount of money Janet has represented by the fraction 5 / 15 of the total ratio is 5 / 15 * $75 = $25. Combined, Cara and Janet have $20 + 25 = $45. If Cara and Janet buy goods worth $45 and sells them at 80% of the buying price, the selling price of the goods will be 80 / 100 * $45 = $36. Since they bought the goods at $45 and sold them at $36, Janet and Cara would run at a loss of $45 - $36 = $9.
The answer: 9

Question: The ratio of the amount of money Cara, Janet, and Jerry have is 4:5:6. If the total amount of money they have is $75, calculate the loss Cara and Janet will make if they combine their money to buy oranges and sell them at 80% of the buying price.
He gets 30% off any book over $22 and he buys books that cost $25.00 and $35.00 so the total cost of these books is $25 + $35 = $60.00. At 30% off, the discount on these books is $60 * .30 = $18.00. That mean these 2 books will cost $60 - $18 = $42.00. He gets 20% off any book under $20 and he buys books for $18.00, $12.00 and $10.00 so these books together cost $18 + $12 + $10 = $40.00. at 20% off, the discount on these books is 40 * .20 = $8.00. So these 3 books will cost $40 - $8 = $32.00. He has spent $42.00 on the two most expensive books, $32.00 on the 3 cheapest books, and also bought a book for $21.00, so his total comes to $42 + $32 + $21 = $95.00.
The answer: 95
Reverse engineering the question: To make room for a new inventory of books, Gordon's local bookstore is offering 30% off any book that is over $22.00 and 20% off any book under $20.00. He buys several books with the following prices; $25.00, $18.00, $21.00, $35.00, $12.00 and $10.00. How much will he spend on books?
Reasoning and answer: He increased his speed by 150 * .3 = 45 mph. So his new speed was 150 + 45 = 195 mph. He increased it a further 10 mph so his new speed is 195 + 10 = 205 mph.
The answer: 205

Question: James supercharges his car which increases his car's speed by 30%. He then cuts weight by 15% which increases the speed a further 10 mph. If his car's original speed was 150 mph what is the new speed?
Reasoning and answer: The cost of Gary's gold is 30 * $15 = $450. The cost of Anna's gold is 50 * $20 = $1000. The total cost of their gold is $450 + $1000 = $1450.
The answer: 1450
