#include <iostream>
using namespace std;

int main() {
    double a;
    int times = 5;
    double totalDistance = 0.0;
     
    while (cin >> a) { // 注意 while 处理多个 case
         while(times > 0)
         {
            totalDistance += a * 1.5;
            a /= 2;
            --times;
         }
         cout << totalDistance - a << endl;
         cout << a;

    }
}
// 64 位输出请用 printf("%lld")
