 #include <iostream>
 #include <cstdio>
 #include <cstring>
 using namespace std;
 int main()
 {
     float a,sum;
     while (cin>>a)//要注意格式，能从文件读入多组数据！
     {
         sum=a;
         for (int i=;i<;i++)
         {
             cin>>a;
             sum+=a;
         }
         cout<<'$'<<sum/<<endl;
     }

     return ;
  }
