messages.content: Percentage means per 100, so if she still owes 75%, she must have paid 100% - 75% = 25% of the original amount.
  25% of the original amount = (25/100)*original amount = $125
  Multiplying both sides by (100/25) gives: original amount = (100/25)*$125 = $<<(100/25)*125=500>>500
  #### 500
