#include<stdio.h>
void main()
{
  double I,Q;int t;
  scanf("%lf",&I);
  if(I<0)printf("it is not right);
  else
      {
        t=I/100000;
        switch(t)
       { case 0:Q=0.1*I;break;
         case 1:Q=0.1*100000+0.075*(I-100000);break;
         case 2:
         case 3:Q=0.1*100000+0.075*100000+0.05*(I-200000);break;
         case 4:
         case 5:Q=0.1+100000+0.075*100000+0.05*200000+0.03*(I-400000);break;
         case 6:
         case 7:
         case 8:
         case 9:Q=0.1*100000+0.075*100000+0.05*200000+0.03*200000+0.015*(I-600000);break;
       }
     if(t>=10)Q=0.1*100000+0.075*100000+0.05*200000+0.03*200000+0.015*400000+0.01*（I-1000000);
    printf("Q=%Lf\n",Q);
  }
