#include<iostream>

using namespace std;

int main(){

float itemCost,numOfitems,discount,tax=7,tcost,costaftdisc;

cout << "Enter ItemCost:";

cin >> itemCost;

cout << "Enter number of items:";

cin >> numOfitems;

cout << "Enter discount:";

cin >> discount;
  
tcost = itemCost*numOfitems;

cout << "Total Cost before discount : " << (tcost) + (tcost)*(tax/100) << endl;

cout << "Total Cost before tax : " << (itemCost*numOfitems) << endl;
  
cout << "Discount amount : " << (tcost)*(discount/100) << endl;
  
costaftdisc = (tcost) - (tcost)*(discount/100) ;

cout << "Total Cost After discount : " << costaftdisc << endl;

cout << "Tax amount : " << (costaftdisc)*(tax/100) << endl;

cout << "Final cost : " << (costaftdisc) + (costaftdisc)*(tax/100) << endl;
  
return 0;

}
/*
