Draw the GUI that the statements in method creates. (6) Complete the method itemStateChanged in . First obtain the value of the total amount of the order as well as the delivery method selected. Then calculate the final amount due as follows: (5) If the delivery method is priority, then the final amount is the order amount + 20%. If the delivery method is express, then the final amount is the order amount + 10%. If the delivery method is standard, and the order amount is greater than R75.00, then the final amount is the order amount, else add 5% to the final amount.
