帮您稍作整理
```
include<stdio.h>
const int N=3;
int main()
{
int n,a,b,num,money,min,i;
short price[3];
scanf("%d",&n);
for(i=0;i<=N;i++)
{
scanf("%d %d\n",&a,&b);
if((n%a)==0)
{
num=n/a;
}
else
{
num=n/a+1;
}
money=num*b;
price[i]=money;
for(i=1;i<=N;i++)
{
if(price[(i-1)]<money)
{
min=price[(i-1)];
}
else min=money;
}
} printf("%d",min);
return 0;
}

```cpp
#include<bits/stdc++.h>
using namespace std;
double sum1,sum2,sum3,m;
int a[4],b[4],n;
int main () {
cin>>n;
for (int i=1;i<=3;i++) cin>>a[i]>>b[i];
sum1=ceil(n*1.0/a[1])*b[1];
sum2=ceil(n*1.0/a[2])*b[2];
sum3=ceil(n*1.0/a[3])*b[3];
m=sum1;
if (m>=sum2) m=sum2;
if (m>=sum3) m=sum3;
cout<<int(m)<<endl;
return 0;
}
