Question: Inez has $150. She spends one-half on hockey skates and a certain amount on hockey pads. If Inez has $25 remaining, how much did the hockey pads cost, together, in dollars?
Answer: Step-by-step reasoning process: She spent 150 / 2 = $75 on hockey skates. Let X be the amount Inez spent on hockey pads. 150 - 75 - X = 25. 75 - X = 25. X = 50. The hockey pads cost $50.
So the answer is 50.

Question: There are three times as many girls as boys in the Biology class. The Physics class has 200 students. If the Biology class has half as many students as the Physics class, how many boys are in the Biology class?
Answer: Step-by-step reasoning process: The Biology class has 200 / 2 = 100 students. The boys in the Biology class are 1 / 4 * 100 = 25 students.
So the answer is 25.

Question: Janeth bought 5 bags of round balloons with 20 balloons in each bag. She also bought 4 bags of long balloons with 30 balloons in each bag. While blowing up the balloons, 5 round balloons burst. How many balloons are left?
Answer: Step-by-step reasoning process: Janeth bought 5 x 20 = 100 round balloons. She bought 4 x 30 = 120 long balloons. So, she has a total of 100 + 120 = 220 balloons. Since 5 round balloons burst, then there are only 220 - 5 = 215 balloons left.
So the answer is 215.

Question: Barbara got a great deal on a new chest of drawers, but she has to take a lot of paper out of the drawers to be able to use it. She found 3 bundles of colored paper, 2 bunches of white paper, and 5 heaps of scrap paper. If a bunch holds 4 sheets of paper, a bundle holds 2 sheets of paper, and a heap holds 20 sheets of paper, how many sheets of paper did Barbara remove from the chest of drawers?
Answer:
Step-by-step reasoning process: Of the colored paper, Barbara removed 3 * 2 = 6 sheets of paper. Of the white paper, she removed 2 * 4 = 8 sheets of paper. Of the scrap paper, she removed 5 * 20 = 100 sheets of paper. So in total, Barbara removed 6 + 8 + 100 = 114 sheets of paper.
So the answer is 114.
