Answer the following question.
A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars?
Step-by-step reasoning process: The 2 players are sold for a total of 2 * 10 = $20 million. So the club has 100 + 20 = $120 million. The cost of buying 4 more players at $15 million each is 4 * 15 = $60 million. So the club now has 120 60 = $60 million.
The answer is 60.

Answer the following question.
Kyle bakes 60 cookies and 32 brownies. Kyle eats 2 cookies and 2 brownies. Kyle's mom eats 1 cookie and 2 brownies. If Kyle sells a cookie for $1 and a brownie for $1.50, how much money will Kyle make if he sells all of his baked goods?
Step-by-step reasoning process: Kyle and his mom eat a total of 2 + 1 = 3 cookies. Kyle and his mom eat a total of 2 + 2 = 4 brownies. The number of cookies remaining is 60 - 3 = 57 cookies. The number of brownies remaining is 32 - 4 = 28 brownies. From selling his cookies, Kyle makes 57 * $1 = $57. From selling his brownies, Kyle makes 28 * $1.50 = $42. Kyle would make a total of $57 + $42 = $99 if he sold all of his baked goods.
The answer is 99.

Answer the following question.
Harry is counting the hours that he sleeps. On Monday night, he sleeps for 8 hours. On Tuesday night, he sleeps for 7 hours. On Wednesday night, he sleeps for 8 hours. On Thursday night, he sleeps for 10 hours. On Friday night he sleeps for 7 hours. What is the average number of hours that Harry sleeps in one night?
Step-by-step reasoning process: Across Monday through Friday, the total number of hours Harry sleeps is 8 + 7 + 8 + 10 + 7 = 40 hours. The total number of days from Monday through Friday is 5 days. The average number of hours Harry sleeps in one night is 40 / 5 = 8 hours.
The answer is 8.

Answer the following question.
At the beginning of an academic year, there were 15 boys in a class and the number of girls was 20% greater. Later in the year, transfer students were admitted such that the number of girls doubled but the number of boys remained the same. How many students are in the class now?
Step-by-step reasoning process: The original number of girls was 20% greater than 15 (the number of boys) giving 15 + (20 / 100) * 15 = 18. After the admission of transfer students, the number of girls doubled to become 18 * 2 = 36. In addition to the 15 boys, there are now 15 + 36 = 51 students in the class.
The answer is 51.
