Reasoning and answer: The tickets are $50.00 each and they need 2 tickets so that's 50 * 2 = $100.00. There is a 15% processing fee for the tickets so that's 100 * .15 = $15.00. The tickets are $100.00 and the processing fee is $15.00 for a total of 100 + 15 = $115.00. There is a $5.00 per person entrance fee and there are 2 people so that's 5 * 2 = $10.00. The tickets are $115.00, parking is $10.00 and the entrance fee is $10.0 for a total of 115 + 10 + 10 = $135.00.
The answer: 135

Question: Seth and his brother want to see their favorite band in concert. The tickets are $50.00 each. There is a 15% processing fee for the tickets. They are also charged $10.00 for parking and an additional $5.00 per person entrance fee. How much will it cost to go to the concert?


Lovely will sell 10 x 2 / 5 = 4 books for $2.50 each. She will sell 10 - 4 = 6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $10. Her earnings for the 6 books for $2 each will be $2 x 6 = $12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22.
The answer: 22
Reverse engineering the question: A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?


Reasoning and answer: By the first two months, 20 / 100 * 200 = 40 mountains had erupted. The total number of mountains remaining after the first round of explosions is 200 - 40 = 160. When 40% of the remaining mountains exploded, the number of mountains that were still intact decreased by 40 / 100 * 160 = 64. The number of mountains that hadn't exploded after the second explosions is 160 - 64 = 96. When 50% of the mountains which were still intact exploded, the number of mountains that hadn't erupted was reduced by 50 / 100 * 96 = 48. At the end of the year, 96 - 48 = 48 mountains remained intact and hadn't exploded.
The answer: 48
What was the question?
Question: A mountain range has 200 active volcanoes. In a particular year, 20% of the volcanoes exploded in the first two months, 40% of the remaining exploded by the half of the year, and at the end of the year, another 50% of the volcanoes that hadn't already erupted also exploded. How many mountains are still intact at the end of the year?


Tilly will make 100 x $10 = $1000 in total. She has spent $1000 - $300 = $700 on 100 bags. Each bag cost Tilly $700 / 100 = $7.
The answer: 7
Reverse engineering the question: Tilly needs to sell 100 bags at $10 per bag to make $300 in profit. How much did she buy each bag for?


Reasoning and answer: First find how many onions total Trent needs to chop: 4 onions / pot * 6 pots = 24 onions. Then divide that number by three onions per 2 tears to find how many sets of two tears Trent cries: 24 onions / 3 onions = 8. Then multiply that number by the number of tears per set to find the total number of tears: 8 * 2 tears = 16 tears.
The answer: 16

Question: Trent cries 2 tears for every three onions he chops. He needs to chop 4 onions per pot of soup. If he's making 6 pots of soup, how many tears does he cry?


Reasoning and answer: 12 + 5 + 5 + 2 = 24 minutes are accounted for. There are 30 - 24 = 6 minutes of ads.
