Question

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. Design a modular program that asks the user to enter the total sales for the month. From this figure, the application should 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 pseudocode, represent the county tax rate (0.02) and the state tax rate (0.04) as named constants.
