t应该是t+，有12个月的

```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int s=0;
int t=0;
for(int i=1;i<=12;i++){
int x;
cin>>x;
if(x<=s+300){
s+=300-x;
}else{
cout<<'-'<<i<<endl;
return 0;
}
if(s/100>=1){
t+=s/100*100;
s-=s/100*100;
}
}
cout<<t*1.2+s<<endl;
return 0;
}//这是我的方法

```cpp
var
i,ch,money,x,t:longint;
f:boolean;
begin
f:=true;
for i:=1 to 12 do begin
readln(x);
money:=money+300-x;
if money<0 then begin
f:=false;t:=i;
end;
ch:=ch+money div 100;
money:=money mod 100;
end;
money:=money+ch*120;
if f then writeln(money)
else writeln(-t);
end.
为什么也是80分
