    public static void main(String args[]) {
        int vegBurgerCost = 4 * 45;
        int vegMcPuffCost = 3 * 25;
        int total = vegBurgerCost + vegMcPuffCost;
        int amt = total - 50;
        System.out.println("4 Vegetable Burgers @ 45 = " + vegBurgerCost);
        System.out.println("3 Vegetable McPuffs @ 25 = " + vegMcPuffCost);
        System.out.println("Total = " + total);
        System.out.println("Discount = 50");
        System.out.println("Final Bill = " + amt);
