conversations.value: An internet provider gives a 5% discount if the customer pays before the 25th day of the month. If the monthly internet rate is $50, how much did the customer pay in all for 4 months if he paid every 25th of the month?
  Give me a clear explanation.

conversations.value: The 5% discount amounts to $50 x 5/100 = $2.50.
  So the total discount given to the customer for 4 months was $2.50 x 4 = $10.
  The customer was supposed to pay $50 x 4 = $200 in all for 4 months without discount.
  Since the customer is entitled to the discount, then he only paid a total of $200 - $10 = $190 for 4 months.
