When a customer registers for a workshop, he or she must pay the registration fee plus the lodging fees for the selected location.  For example, here are the charges to attend the Supervision Skills workshop in Orlando:

Registration: $1,500

Lodging: $300 X 3 days = $900

Total: $2,400

Create an application that lets the user select a workshop from one ListBox and a location from another ListBox.  When the user clicks a button, the application should calculate and display the registration cost, the lodging cost and the total cost.

Extra Credit 

Add a discount check box that can be used for premier members.  These users get a 10% discount off the registration fee, but not off the lodging.
