```cpp
#include<iostream>
#include<cstdio>
//#include<iomanip>
using namespace std;
int main(){
int wat;
double money;
cin >> wat;
if (wat <= 150){
money = wat*0.4463;
}else if (wat >= 151 && wat <= 400){
money = 150*0.4463+(wat-150)*0.4663;
}else{
money = 150 * 0.4463+(400-150)*0.4663+(wat - 400)*0.5663;
}
printf("%.1f",money);
return 0;
}
```
