Question

Write a Java program named, TicketSale, (TicketSale.java) with the following tasks:

• Prompt user to input the number of Adult tickets to purchase
• Prompt user to input the number of Children tickets to purchase
• Prompt user to input the number of Senior tickets to purchase
• Write a method named, ticketCost(), which will be invoked by main() with statement similar to:

  • cost = ticketCost( adults, children, senior );

• Ticket costs structure:
  • $15.00 for each adult
  • $10.00 for each child
  • $5.00 for each senior
  • Each adult ticket can purchase one child ticket for $5.00
  • If there is at least one adult ticket, all senior tickets can be purchased at $2.00
• Must use System.out.printf() for all output functions
• Sample output:

Please enter number of adults:1
Please enter number of kids:1
Please enter number of seniors:5
Your total cost for 1 adults, 1 children, and 5 seniors is: $30.00

• Sample output:

Please enter number of adults:0
Please enter number of kids:2
Please enter number of seniors:10
Your total cost for 0 adults, 2 children, and 10 seniors is: $70.00
