AC代码：
```cpp
#include<iostream>
using namespace std;
int main()
{
int shuliang, qian, a, b, i;
cin >> shuliang;
qian = 1000000000;
for(i = 1; i <= 3; i++)
{
cin >> a >> b;
if(shuliang % a != 0)//如果不能买整包数
{
if(qian > (shuliang / a + 1) * b)
{
qian = (shuliang / a + 1) * b;
}
}
else if(qian > shuliang / a * b)

qian = shuliang / a * b;
}

cout << qian;
