Answer to Question #261320 in C# for Amily

Question

Create a program that allows bags to be purchased. There are six different types: full decorative, beaded, needlepoint design, fringed beaded and plain. Create a ListBox object for the different styles. After the user makes a selection, display a message indicating which selection was made. Include an option to clear selections. Include a control that allows the user to enter the quantity desired. Include a set of radio buttons that contain shipping options of overnight, three day and standard. The price for each bag is as follows: full decorative R50; beaded – R45; needlepoint design – R40, fringed beaded – R30 and plain – R20. The shipping charges are based on the total purchase. The following percentages are used: Overnight – 10%, three day – 7% and standard – 5%. Display in a message box the shipping charge along with the selection, quantity and total cost.
