Software Sales
A software company sells three packages, Package A, Package B, and Package C, which retail for $99, $199, and $299, respectively. Quantity discounts are given according to the following table:
Quantity | Discount |
10 through 19 20 through 49 50 through 99 100 or more | 20% 30% 40% 50% |
Create an application that allows the user to enter the number of units sold for each software package. The application’s form should resemble Figure 1.
Figure 1 Software Sales from
The application should calculate and display the order amounts and the grand total in a Label control. The Clear button must clear all text boxes and calculated labels. The Exit button must close the window.
Input validation: Make sure the number of units for each package is numeric, and is not negative.
Use the following test data to determine if the application is calculating properly:
Units Sold | Amount of Order |
Package A: 15 units Package B: 75 units Package C: 120 units | Package A: $1,188.00 Package B: $8,955.00 Package C: $17,940.00 Grand Total: $28,083.00 |
