  5. * CALCULATE RESTAURANT BILL
  6. * ____________________________________________________________
  7. * This program calculates the restaurantBill given a 
  8. * totalBill, a taxPercent and a tipPercent.
  9. *
  10. * Computation is based on the formulas:
  11. * billTaxAmount  = restaurantBill * (taxPercent / 100);
  12. * billTipAmount  = (restaurantBill + billTaxAmount) * (tipPercent / 100);
  13. * restaurantBill = totalBill + billTaxAmount + billTipAmount
  14. * ____________________________________________________________
  15. * INPUT
  16. * restaurantBill : Total cost of bill in dollars (as a double EX: 23.76)
  17. * taxPercent     : Percentage of sales tax (as a double EX: 4.7)
  18. * tipPercent     : Percentage bill to be tipped (as a double EX: 2.8)
  19. * 
  20. * PROCESSING
  21. * billTaxAmount  : The amount taxed  (in dollars EX: $4.57)
  22. * billTipAmount  : The amount tipped (in dollars EX: $4.57)
  23. *
  24. * OUTPUT
  25. * billTotal      : The restuarant bills total amount (in dollars EX: $4.57)
