struct  {
int s;
char name[N];
 
 }room[N];
void main()
{ 
int n;
float sum1=0;int sum2=0,sum=0,p;
scanf("%d %d",&n,&p);

 for(int i=0;i<n;i++)
 scanf("%d %s",&room[i].s,room[i].name);

for(i=0;i<n;i++)
sum+=room[i].s;
printf("%d\n",sum);
sum1=(float)sum;
for( i=0;i<n;i++)
{
	if(strcmp("balcony",room[i].name)==0)
     sum1=sum1-(float)room[i].s/2;
	if(strcmp("bedroom",room[i].name)==0)
     sum2=sum2+room[i].s;
}

printf("%d\n",sum2);
printf("%.1f",sum1*(float)p);
 
}
