   Joe's Automotive performs the following routine maintenance services:
   Oil Change- 26.00
   Lube Job – 18.00
   Radiator Flush – 30.00
   Transmission Flush – 80.00
   Inspection – 15.00
   Muffer Replacement – 100.00
   Tire Rotation – 20.00
   Joe also performs other nonroutine ervices and charges for parts and labor (20.00 per hour). Create a GUI application that displays the total for a customers visit to Joe's.
   Everything works out ok but, one thing that it's not working is the Calculation and Exit Buttons. And also im not sure if i did the calculation right so please help on that part too. Thanks
