This is an extra credit assignment.
Create three list boxes. The first is a list of dinner items and their prices. The second is a list of dessert items and their prices. The third is the a list of beverages and their prices.
The user will select zero or more items from each list. There will also be some radio buttons to allow the user to pick what percentage tip they want to use. This should include at least 10%, 15% and 20%.
After they make their choices they will press a button that will total the purchases. You will display the chosen items in a text box along with the prices. At the bottom of the display will be the total of the prices. It will also show the tip amount and the final total.

Yours does not have to look just like that. The position of the controls, their names or the labels on them is not the primary thing. ASK if you aren't sure what I mean or if you want to know if you are going in the right direction.
ASK if you have any questions.
