  3. * CALCULATE MONTHLY INTERNET BILL
  4. * ______________________________________________________________________________
  5. * This program calculates a customer's monthly Internet bill based on the subsc-
  6. * ription package they selected and the number of hours they used during the 
  7. * month.
  8. * 
  9. * This program produces a monthly Internet bill. The Internet bill is based on 
  10. * a selected subscription package, and the number of hours consumed during the 
  11. * billing period.
  12. * 
  13. * Computation is based on the Formula:
  14. * Package A : Base fee includes 10 hours, extra hours are charged
  15. * Package B : Base fee includes 20 hours, extra hours are charged
  16. * Package C : Flat rate with unlimited access (no extra charges)
  17. *______________________________________________________________________________
