conversations.value: Solve the following math problem: Frankie watches TV after he finishes his homework every night. On Monday and Tuesday, he watched a 1-hour episode of his favorite show each night. On Wednesday, he watched a few episodes of a 30-minute show. On Thursday, he finished homework early and watched a 1-hour episode and a 30-minute show. On Friday, he got to stay up late for the weekend, so he watched two 1-hour episodes. If he watched 7 hours of TV in all, how many 30-minute episodes did he watch on Wednesday?

conversations.value: Let W be the number of episodes he watched on Wednesday.
  After Monday, he had 7 - 1 = 6 hours of TV left.
  After Tuesday, he had 6 - 1 = 5 hours of TV left.
  After Thursday, he had 5 - 1 - 1/2 = 3 1/2 hours of TV left.
  After Friday, he had 3 1/2 - 2 = 1 1/2 hours of TV left.
  Each 30-minute episode is 1/2 hour.
  Thus, W = 1 1/2 / 1/2 = 3 episodes.
