Q-2 Joe's automotive perform the following routine maintance services:

oil change - $26.00

lube job - $18.00

Radiator flush - $30.00

Transmission flush - $80.00

Inspection - $15.00

Tire rotation - $20.00

Joe also perform other nonroutine service and charges for parts and for labor ($20 per hours). Create a GUI application that displays the total for a customer's visit to Joe's.
