messages.content: Let X be the money Jason had at first.
  Jason spent 1/4*X + 10 on books.
  Jason spent 2/5*[X - (1/4*X + 10)] + 8 on some DVDs.
  Jason has X - (1/4*X + 10) - {2/5*[X - (1/4*X + 10)] + 8} = $130 left.
  X - 1/4*X - 10 - 2/5*X + 1/10*X + 4 - 8 = $130.
  9/20*X - 14 = $130.
  X = $<<320=320>>320.
  #### 320
