#include <cmath>
#include <iostream>
using namespace std;

int main() {
    int h;
    float s[10] = {0};
    float_t sum = 0;

    cin >> h;

    s[1] = h;
    sum += s[1];

    for(int i=2; i<=5; i++)
    {
        s[i] = s[i-1] / 2.0;
        sum += s[i] * 2.0;
    }

    cout << sum << endl;
    cout << s[5]/2.0 << endl;
}
