Monthly Sales Tax
A retail company must file a monthly sales tax report listing the total sales for the month, and the amount of state and county sales tax collected.
The state sales tax rate is 4 percent and the county sales tax rate is 2 percent. Create a GUI application that allows the user to calculate and display the following:
The amount of county sales tax
The amount of state sales tax
The total sales tax (county plus state)
In the application's code, represent the county tax rate (0.02) and the state tax rate (0.04) as named constants.
