She first gave away half of her 20 brownies, or 20 / 2 = 10 brownies, to the faculty. The remaining brownies number 20 - 10 = 10 brownies. She gave half of these remaining brownies, or 10 / 2 = 5 brownies, to Carl. This reduced her number from 10 down to 10 - 5 = 5 brownies. Finally, she gave away another 2, leaving her with 5 - 2 = 3 brownies.
The answer: 3
Reverse engineering the question: Annie brought 20 brownies to school. She gave half of them to the school administrator to put in the faculty lounge. Of the remaining brownies, she gave half to her best friend, Carl, and another two to her friend, Simon. How many brownies did she have left?
Reasoning and answer: He earns $12 + $8 = $20 after selling the French fries and Poutine every day. So, he earns $20 x 7 = $140 every week. And the total amount he pays for the taxes is $140 x 0.10 = $14. So, his income after paying the weekly taxes is $140 - $14 = $126. Lucius spends $10 x 7 = $70 for the ingredients every week. Therefore, his total income every week after buying all the ingredients and paying the taxes is $126 - $70 = $56.
The answer: 56

Question: Lucius owns a small business and spends $10 every day on ingredients. He then makes a portion of French Fries and a portion of Poutine and sells them to the market, paying ten percent of his weekly income as tax. If the price of French fries is $12 and the price of Poutine is $8, how much does he earn every week after paying the taxes, selling all his products, and buying all the ingredients?
Tony walks 3 miles at 3 miles per hour for 3 / 3 = 1 hour. Tony also runs 10 miles at 5 miles per hour for 10 / 5 = 2 hours. Thus, each day he exercises for 1 + 2 = 3 hours. Over the course of one week, he exercises for 3 * 7 = 21 hours.
The answer: 21
Reverse engineering the question: Tony exercises every morning by walking 3 miles carrying a 25-pound backpack, then he runs another 10 miles without the backpack. If he walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour, how many hours each week does he spend exercising?
Reasoning and answer: There are 12 dogs and half are standing on their back legs so that means 12 / 2 = 6 are standing on their back legs. A dog has 2 back legs and only 6 are standing on their back legs meaning that there are 2 * 6 = 12 paws on the ground. The other 6 dogs are standing on all 4 legs which means these 6 dogs have 6 * 4 = 24 paws on the ground. When you add them together 12 + 24 = 36 paws on the ground.
The answer: 36

Question: At the end of a circus act, there are 12 dogs on stage. Half of the dogs are standing on their back legs and the other half are standing on all 4 legs. How many dog paws are on the ground?
After the first evaporation, the water tank has 6000 liters - 2000 liters = 4000 liters. After the second extraction, the water tank has 4000 liters - 3500 liters = 500 liters. The tank is refilled with rain 30 minutes / 10 minutes = 3 times. The amount of water refilled with rain is 3 times * 350 liters per time = 1050 liters. With the additional rainwater, the water tank has 500 liters + 1050 liters = 1550 liters.
The answer: 1550
Reverse engineering the question: A tank contains 6000 liters of water, 2000 liters evaporated, and then 3500 liters were drained by Bob. How many liters are in the tank if it now rains for 30 minutes and every 10 minutes 350 liters of rain are added to the tank?
From selling her tomatoes, she can make 200 * $1 = $200. From selling her carrots, she can make 350 * $1.50 = $525. The total amount of money she can make is $200 + $525 = $725.
The answer: 725
Reverse engineering the question:
Carrie harvested 200 tomatoes and 350 carrots on her farm. If she can sell a tomato for $1 and a carrot for $1.50, how much money can she make if she sells all of her tomatoes and carrots?
