I need help taking the directions from my school project and putting them into a list box without having to manually add the percent each time and I cant say for sure if I will need help setting up the math in a simpler way. This is the directions "Given the food charge for the meal in a textbox the program should calculate the tip charges for each value in the range from 10% - 30% and display each as an item in a list box. The program should also display the tax and total bill depending on which item is selected for tip from the listBox."
