#include<bits/stdc++.h>
using namespace std;
int main(){
    int a;
    double b=0;
    cin>>a;
    if(a<=150){
        b=a*0.4463;
    }
    if(a>150&&a<=400){
        a=a-150;
        b=150*0.4463+a*0.4663;
    }
    else{
        a=a-400;
        b=150*0.4463+250*0.4663+a*0.5663;
    }
    cout<<fixed<<setprecision(1)<<b;
    return 0;
 }
