Consider the question. Calvin and Paislee played a pool game where points were awarded for winning a round. If Calvin had scored 500 points and Paislee 3/4 times as many points as Calvin, how many points was Paislee required to achieve to have a chance of tying the game?
 If the answer is '125'; explain the reasoning:
If Calvin had scored 500 points and Paislee 3 / 4 times as many points as Calvin, Paislee had scored 3 / 4 * 500 = 375 points. To have a chance of tying the game, Paislee had to score 500 - 375 = 125 points.
