Question: Shara borrowed money from her brother 6 months ago. She returned $10 per month to her brother. Currently, she was able to return half of the money she borrowed. How much will she still owe her brother 4 months from now?
Answer: Step-by-step reasoning process: For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now.
So the answer is 20.

Question: Reynald is the head of the varsity department, and he bought 145 balls. Twenty were soccer balls. There were five more basketballs than the soccer balls. Twice the number of soccer balls were tennis balls. There were ten more baseballs than the soccer balls, and the rest were volleyballs. How many were volleyballs?
Answer:
Step-by-step reasoning process: There were 20 + 5 = 25 basketballs. There were 2 x 20 = 40 tennis balls. And, there were 20 + 10 = 30 baseballs. So, there were 20 + 25 + 40 + 30 = 115 soccer balls, basketballs, tennis balls and baseball altogether.                      Therefore, Reynald bought 145 - 115 = 30 volleyballs,.
So the answer is 30.
