#include<bits/stdc++.h>
using namespace std;

int main()
{
	int g,money = 8;
	char ji;
	cin>>g>>ji;
	if(g <= 1000) 
	{
		cout<<money;
		return 0;
	}
	int tg = g - 1000;
	if(tg % 500 > 0)
	{
		money += tg/500*4;
		money += 4;
	}
	else money += tg/500*4;
	if(ji == 'y') money += 5;
	cout<<money;
	return 0; 
}
