how do I design a program using a flowchart, the program needs to compute state and county sales tax? It is suppose to compute it once the user enters amount of purchase

To design a program using a flowchart to compute the state and county sales tax based on the user's entered amount of purchase, you can follow these steps:

1. Start: Begin designing the flowchart by placing the start symbol at the top of the page.
2. Input: Add a symbol to represent the input operation, which will prompt the user to enter the amount of purchase.
3. Process: Next, include a symbol to calculate the state sales tax. This can be done by multiplying the amount of purchase by the state sales tax rate.
4. Process: Similarly, include another symbol to calculate the county sales tax by multiplying the amount of purchase by the county sales tax rate.
5. Process: Add a symbol to calculate the total sales tax by adding the state and county sales taxes together.
6. Output: Include a symbol to display the total sales tax calculated to the user.
7. End: Finally, add an end symbol to denote the end of the program.

Here is a textual representation of the flowchart for better understanding:

```
Start
|
V
Input (Amount of Purchase)
|
V
Process (Calculate State Sales Tax)
|
V
Process (Calculate County Sales Tax)
|
V
Process (Calculate Total Sales Tax)
|
V
Output (Total Sales Tax)
|
V
End
```

By following this flowchart, you can design a program that prompts the user to input the amount of purchase and computes the state and county sales taxes, resulting in the total sales tax amount.
