import java.util.Scanner;

public class day6code2 {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        double price=sc.nextDouble();
        int month=sc.nextInt();
        String type=sc.next();
        double num=price(price,month,type);
        System.out.println("优惠价是"+num);
    }
    public static double price(double price,int month,String type){
        if(month>=5&&month<=10){
            switch(type){
                case "头等舱":
                    price*=0.9;
                    break;
                case "经济舱":
                    price*=0.85;
                    break;
            }
        }else{
            switch(type){
                case "头等舱":
                    price*=0.7;
                    break;
