#include <stdio.h>

int main(int argc, char *argv[])
{
    int a = 1,b = 0,day = 0;//a为当天买的数量，b为一共买的数量 ，day为天数 
    while(1) 
    {
        day++;
        a = a*2;
        if(a+b>100) break; 
        b = a+b;
        
    }
    //printf("%d",day);
    float money;
    money = (float)80/day;//80为总100个的总价，money为平均每天的价格 
    printf("%f\n",money);
    return 0;
