//Description
//Tony and his friends decided to rent a boat - the rent depends on the season and the number of fishermen.
//The price on the basis of season:
//Spring - 3000 $
//Summer and autumn - 4200 $
//Winter - 2600 $
//The price on the basis of number of fishermen uses discount:
//If the group is up to 6 people (inclusive) - 10% discount
//If the group members are in range [7…11] - 15% discount
//If the group is 12 or more people - 25% discount
//The fishermen use another 5 % discount if they are even number except when it is NOT autumn – then they do NOT have additional discount.
//Write a program to calculate whether the fishermen will gather enough money.
//Input
//The input is consists of exactly 3 lines:
//The budget of the group - real number in range [1…8000]
//Season - String : "Spring", "Summer", "Autumn", "Winter"
//Number of fishermen - integer in range [4…18]
//Output
//Print on the console a single line:
//If the budget IS enough: "Yes! You have {money left} dollars left."
//If the budget IS NOT enough: "Not enough money! You need {money needed} dollars."
//The prices should be formatted to the second decimal point.

//Example               Input
//30000                 Not enough money! You need 570.00 dollars
//Summer
//11

//Comments
//In the summer fishing costs 4200$,
//11 fishermen take 15% discount -> 4200 - 15% = 3570 $, their number is odd so they do not use additional discount.
//3000 <= 3570, hence they need 570.00 $ more

//Example
//Input	            Output
//2000              Yes! You have 50.00 dollars left.
//Winter
//13

//Example
//Input             Output
//3600              Yes! You have 1035.00 dollars left.
