Answer 1

#include <iostream>

using namespace std;

int findDiscount(int quantity) {
    if(quantity == 5) {
        return 8;
    }
    if(quantity == 6) {
        return 10;
    }
    if(quantity == 7) {
        return 12;
    }
    if(quantity == 8) {
        return 15;
    }
    if(quantity == 9) {
        return 17;
    }
    if(quantity == 10) {
        return 20;
    }
    return 0;
}
int main() {
    string name;
    int q;

    cout << "Enter company: ";
    cin >> name;

    cout << "Enter number of games purchased: ";
    cin >> q;
    while(q < 5 || q > 10) {
        cout << "invalid quantity. try again." << endl;
        cout << "Enter number of games purchased: ";
        cin >> q;
    }

    int discount_perc = findDiscount(q);

    double amount_discount = q * 20 * discount_perc / 100;
    double cost_purchase = q * 20 - amount_discount;

    cout << "Total discount: " << amount_discount << endl;
    cout << "Cost of purchase: " << cost_purchase << endl;
}
