  1. //Description
  2. //Tony and his friends decided to rent a boat - the rent depends on the season and the number of fishermen.
  3. //The price on the basis of season:
  4. //Spring - 3000 $
  5. //Summer and autumn - 4200 $
  6. //Winter - 2600 $
  7. //The price on the basis of number of fishermen uses discount:
  8. //If the group is up to 6 people (inclusive) - 10% discount
  9. //If the group members are in range [7…11] - 15% discount
  10. //If the group is 12 or more people - 25% discount
  11. //The fishermen use another 5 % discount if they are even number except when it is NOT autumn – then they do NOT have additional discount.
  12. //Write a program to calculate whether the fishermen will gather enough money.
  13. //Input
  14. //The input is consists of exactly 3 lines:
  15. //The budget of the group - real number in range [1…8000]
  16. //Season - String : "Spring", "Summer", "Autumn", "Winter"
  17. //Number of fishermen - integer in range [4…18]
  18. //Output
  19. //Print on the console a single line:
  20. //If the budget IS enough: "Yes! You have {money left} dollars left."
  21. //If the budget IS NOT enough: "Not enough money! You need {money needed} dollars."
  22. //The prices should be formatted to the second decimal point.
  23.  
  24. //Example Input
  25. //3000 Not enough money! You need 570.00 dollars
  26. //Summer
  27. //11
  28.  
  29. //Comments
  30. //In the summer fishing costs 4200$,
  31. //11 fishermen take 15% discount -> 4200 - 15% = 3570 $, their number is odd so they do not use additional discount.
  32. //3000 <= 3570, hence they need 570.00 $ more
  33.  
  34. //Example
  35. //Input Output
  36. //2000 Yes! You have 50.00 dollars left.
  37. //Winter
  38. //13
