Reasoning & answer: CoT: Jennifer has 2 * 10 = 20 apples. She has a total of 10 + 20 + 20 = 50 fruits. She gives her sister 2 pears + 2 oranges + 2 apples = 6 fruits. After giving her sister 2 of each fruit, she has 50 - 6 = 44 fruits left.
The answer: 44
Question: Jennifer has ten pears, 20 oranges, and twice as many apples as pears. If she gives her sister two of each fruit, how many fruits does she have left?

Reasoning & answer: CoT: Fred spent $236 - $14 = $222 on books. The cost per book is $222 / 6 books = $37.
The answer: 37
Question: Fred had 236 dollars to spend on 6 books. After buying them, he had 14 dollars. On average, how much did each book cost?

Reasoning & answer: CoT: He sold each DVD for 6 * 2.5 = $15. So he makes a profit of 15 - 6 = $9. So each day he makes a profit of 9 * 500 = $4500. So he makes 4500 * 5 = $22,500. He makes 22,500 * 20 = $450,000. Then after the cost of creating the movie he has a profit of 450,000 - 2000 = $448,000.
The answer: 448000
Question: James creates a media empire. He creates a movie for $2000. Each DVD cost $6 to make. He sells it for 2.5 times that much. He sells 500 movies a day for 5 days a week. How much profit does he make in 20 weeks?

Reasoning & answer: CoT: If x is Maria's age, then Mario's age is x + 1. The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old.
The answer: 4
Question:
The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria. How old is Mario?
