Answer 1

package stock;

import java.util.Scanner;

public class Stock {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in); // object to take input
        //prompting the user with required output
        System.out.println("Demon software and computers is offering discounts on the Vic Package. This package includes a \n computer and needed software to perform basic daily functions. The Vic package sells for $75.00.\n Discounts are given based on quantity. The discounts are listed below:");
        System.out.println("10 - 19 gives a 20% discount");
        System.out.println("20 - 49 gives a 30% discount");
        System.out.println("50 - 99 gives a 40% discount");
        System.out.println("100 or more gives a 50% discount");
        System.out.println("How many would you like to purchase?");
        int quantity = sc.nextInt(); //taking quantity input
        
        double purchase;
        purchase = quantity * 75; //calculating price
        
        //giving discount according to order
        if(quantity >= 10 && quantity <= 19)
            purchase = purchase - (purchase * 0.20);
        
        if(quantity >= 20 && quantity <= 49)
            purchase = purchase - (purchase * 0.30);
        
        if(quantity >= 50 && quantity <= 99)
            purchase = purchase - (purchase * 0.40);
        
        if(quantity >= 100)
            purchase = purchase - (purchase * 0.50);
        
        //required output
        System.out.println("You purchased " + quantity + " packages. Your total is $" + purchase);
    }
    
}

\n is use in print statement to break line so that the bigger line can be printed and can be adjusted in output window,
