#include<iostream>
using namespace std;
int getDiscount(int quantity,int price){
                int total = quantity * price;
                
                if(quantity>=10 && quantity<20)
                        return total * 0.2;
                if(quantity>=20 && quantity<50)
                        return total * 0.3;
                if(quantity>=50 && quantity<100)
                        return total * 0.4;
                if(quantity>=100)
                        return total * 0.5;
                return 0;
}
int main(){
        const int PRICEA=99;
        const int PRICEB=199;
        const int PRICEC=299;
        int quantityA,quantityB,quantityC;
        cout<<"Enter quantity for package A: ";
        cin>>quantityA;
        cout<<"Enter quantity for package B: ";
        cin>>quantityB;
        cout<<"Enter quantity for package C: ";
        cin>>quantityC;
        int totalA= quantityA * PRICEA-getDiscount(quantityA,PRICEA);
        int totalB= quantityB * PRICEB-getDiscount(quantityB,PRICEB);
        int totalC= quantityC * PRICEC-getDiscount(quantityC,PRICEC);
        int grandTotal = totalA + totalB + totalC;
        cout<<"Package A: "<<quantityA<<" units Package A: $"<<totalA<<endl;
        cout<<"Package B: "<<quantityB<<" units Package B: $"<<totalB<<endl;
        cout<<"Package C: "<<quantityC<<" units Package C: $"<<totalC<<endl;
        cout<<"Grand Total: $:"<<grandTotal;
        
}
