bo1=100000*0.1;
b2=b1+100000*0.075;
b4=b2+200000*0.05;
b6=b4+200000*0.03;
b10=b6+400000*0.015;

scanf("%d",&i);
branch=i/100000;
if (branch>10)  branch=10;
switch(branch)
{  case 0:d=i*0.1;break;
case 1:d=b1+(i-100000)*0.075;break;
case 2:
case 3: d=b2+(i-200000)*0.05;break;
case 4:
case 5:d=b4+(i-400000)*0.03;break;
case 6:
case 7:
case 8:
case 9:d=b6+(i-600000)*0.015;break;
case 10: d=b10+(i-1000000)*0.01;
}
