Reasoning and answer: Rebecca bought 3 * 6 = 18 bottles of soda. A week is 7 days, so she will drink 4 * 7 = 28 half bottles of soda in four weeks. A bottle is two half bottles, so she will drink 28 / 2 = 14 bottles of soda in four weeks. Thus, after 4 weeks, she will have 18 - 14 = 4 bottles of soda left.
The answer: 4

During the weekdays it was visited by 100 * 5 = 500 people. On Sunday and Saturday, it was visited by 200 + 300 = 500 people. In total 500 + 500 = 1000 people visited the park in a week. So it earned 1000 * 3 = 3000 dollars in a week.
The answer: 3000
Reverse engineering the question: An amusement park sells tickets for $3. This week it welcomed 100 people per day but on Saturday it was visited by 200 people and on Sunday by 300. How much money did it make overall in a week?


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.

Reasoning and answer: First find the distance to the second friend's house by halving the distance to the first friend's house: 8 miles / 2 = 4 miles. Then add that amount to the distance to the first friend's house: 4 miles + 8 miles = 12 miles. Then triple that number to find the distance from the second friend's house to work: 12 miles * 3 = 36 miles.
The answer: 36

Question: Danny helps his friends carpool to work. He has to drive 8 miles to the first friend's house, half that distance to the second friend's house, then 3 times the total distance driven so far to get to work. How many miles does Danny drive between the second friend's house and work?


Reasoning and answer: He sells each computer for 1.4 * 800 = $1120. That means he makes a profit of 1120 - 800 = $320 per computer. So he makes 320 * 60 = $19200 from selling computers. He has extra expenses of 5000 + 3000 = $8000 a month. So his profit is 19200 - 8000 = $11,200.
The answer: 11200
