#include<stdio.h>
int main(){
    float a[120];
    int count=0;
    for(int i=0;i<=5;i++){
        for(int j=0;j<=4;j++){
            for(int k=0;k<=6;k++){
                float sum=0.8*i+j+1.8*k;
                bool flag=true;
                for(int l=0;l<count;l++){
                    if(sum==a[l]) {
                        flag=false;
                        break;
                    }
                }
                if(flag) {
                    a[count]=sum;
                    count++;   
                }
            }

    printf("%d\n",count-1);
    return 0;
