Answer the following question.
Xavier plays football with his friends. During 15 minutes Xavier can score 2 goals on average. How many goals on average is Xavier able to score, when the match lasted for 2 hours?
Step-by-step reasoning process: Two hours means 2 * 60 = 120 minutes. So in 2 hours, there are with 120 / 15 = 8 groups of 15 minutes. So on average Xavier can score 8 * 2 = 16 goals.
The answer is 16.

Answer the following question.
Mark went to a store where he spent one-half of his money, and then spent $14 more. He then went to another store where he spent one-third of his starting money, and then spent $16 more. If he then had no money left, how much did he have when he entered the first store?
Step-by-step reasoning process: Let X be the money Mark had. Mark spent 1 / 2 * X + 14 in the first store and 1 / 3 * X + 16 in the second store. Mark has X - 1 / 2 * X - 14 - 1 / 3 * X - 16 = $0 left. Combining like terms, we get 1 / 6 * X - 30 = $0. Adding 30 to both sides and multiplying both sides by 6, we find that Mark had X = $180 when he entered the first store.
The answer is 180.

Answer the following question.
It took Alice three months to save up to buy new shoes. If she saved 10 dollars the first month and 30 more each month, how much did she have saved by the end of the third month?
Step-by-step reasoning process: The first month she saved 10 dollars. By the second month, she had 10 + 30 = 40 dollars saved. By the third month, she had 40 + 30 = 70 dollars saved.
The answer is 70.

Answer the following question.
In a triangle with angles A, B, and C, A is 60 degrees, and B is two times as big as C. Calculate the angle of B.
Step-by-step reasoning process: Since the angles in a triangle adds up to 180, and A is 40 degrees, B and C have a total of 180 - 60 = 120 degrees. Since B is two times bigger than C, the total of the angles of B and C is equal to 2C + C = 120. 3C = 120. The angle of C is C = 120 / 3. C is 40. Since B is two times as big as C, B is 2 * 40 = 80 degrees.
The answer is 80.
