            totalSaleAmount += ticketPrice * ticketsSold;
          
            //repeat for next line
        }
      
        //Output the number oftickets sold and the total sale amount
        System.out.println("Number oftickets sold: " + totalTicketsSold);
        System.out.printf("Total sale amount: $%.2f ", totalSaleAmount);
