#include <iostream>

using namespace std;

int main(){
    int test;
    cin>>test;
    while(test--){
        int x,y,z,k,s;
        cin>>x>>y>>z>>k>>s;
        for (int i=0;i<s;++i) {
            if(x<k){
                x+=y;
            }else{
                x-=z;
            }
        }
        cout<<x<<endl;
