public interface Car {
    String getName();

    double getPrice();
}

public class BMW implements Car{
    @Override
    public String getName() {
        return "BMW";
    }

    @Override
    public double getPrice() {
        return 100;
    }
}

public class Murati implements Car{
    @Override
    public String getName() {
        return "Murati";
    }

    @Override
    public double getPrice() {
        return 90;
    }
}

public class CarShop {
    private double totalIncome;

    public void sellCar(Car car) {
        System.out.println(car.getName() + " " + car.getPrice());
        totalIncome += car.getPrice();
    }

    public double getTotalIncome() {
        return totalIncome;
    }
}

public class Main {
    public static void main(String[] args) {
        CarShop carShop = new CarShop();
        BMW bmw = new BMW();
        Murati murati = new Murati();

        carShop.sellCar(bmw);
        carShop.sellCar(murati);
        System.out.println("Total income: " + carShop.getTotalIncome());
    }
}
