messages.content: Let G stand for the number of GB billed, so the total bill is $0.25G + $45 flat rate charge = $65 total bill.
  Now we will solve for G. $0.25G + $45 flat rate - $45 = $65 -$45. This simplifies to $0.25G = $20
  $0.25G/$0.25 = $20/$0.25
  G = 80 GB were charged on this bill.
  #### 80
