#include<bits/stdc++.h>

using namespace std;

int main() {

    int profit = 0;

    float award = 0;

    cin >> profit;

    if(profit < 0) {

        return -1;

    } else if(profit <= 100000) {

        award = 0.1 * profit;

    } else if(profit <= 200000) {

        award = 0.075 * (profit - 100000) + 10000;

    } else if(profit <= 400000) {

        award = 0.05 * (profit - 200000) + 17500;

    } else if(profit <= 600000) {

        award = 0.03 * (profit - 400000) + 27500;

    } else if(profit <= 1000000) {

        award = 0.015 * (profit - 600000) + 33500;

    } else {

        award = 0.01 * (profit - 1000000) + 39500;

    }

    cout << award << endl;

    return 0;

}
