Design a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county tax. Assume the state sales tax is 4 percent (.04) and the county tax is 2 percent (.02). The program should display the amount of the purchase, the state sales tax, the county sales tax, the total sales tax, and the total of the sale (which is the sum of the amount of the purchase plus the total sales tax).

Design a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume that state tax rate is 4 percent and the county sales tax rate is 2 percent. The program should display the amount of the purchase, the state sales tax, the county sales tax, and the total sales tax, and the total of the sale (which is the sum of the amount of purchase plus the total sales tax).Refactor it so the subtasks are modules, then create a modular design.

Hint: Use the value 0.02 to represent 2 percent, and 0.04 to represent 4 percent.

Sure! Here's a step-by-step solution in Python:

1. Start by asking the user to enter the amount of the purchase:
```python
purchase_amount = float(input("Enter the amount of the purchase: "))
```

2. Calculate the state sales tax (4% of the purchase amount):
```python
state_sales_tax = 0.04 * purchase_amount
```

3. Calculate the county sales tax (2% of the purchase amount):
```python
county_sales_tax = 0.02 * purchase_amount
```

4. Calculate the total sales tax (sum of state and county sales taxes):
```python
total_sales_tax = state_sales_tax + county_sales_tax
```

5. Calculate the total of the sale (sum of purchase amount and total sales tax):
```python
total_sale = purchase_amount + total_sales_tax
```

6. Display the results:
```python
print("Amount of Purchase: $", purchase_amount)
print("State Sales Tax: $", state_sales_tax)
print("County Sales Tax: $", county_sales_tax)
print("Total Sales Tax: $", total_sales_tax)
print("Total Sale: $", total_sale)
```

And that's it! This program will ask the user for the purchase amount, calculate the state and county taxes, and display the required values.

To design a program that calculates the state and county tax for a purchase, you can use the following steps:

1. Prompt the user to enter the amount of the purchase.
2. Read and store the input from the user.
3. Calculate the state sales tax by multiplying the purchase amount by the state tax rate (0.04).
4. Calculate the county sales tax by multiplying the purchase amount by the county tax rate (0.02).
5. Calculate the total sales tax by adding the state sales tax and the county sales tax.
6. Calculate the total of the sale by adding the purchase amount and the total sales tax.
7. Display the amount of the purchase, the state sales tax, the county sales tax, the total sales tax, and the total of the sale.

Here is an example program in Python that implements these steps:

```python
# Prompt the user to enter the amount of the purchase
purchase_amount = float(input("Enter the amount of the purchase: "))

# Calculate the state sales tax
state_tax = purchase_amount * 0.04

# Calculate the county sales tax
county_tax = purchase_amount * 0.02

# Calculate the total sales tax
total_tax = state_tax + county_tax

# Calculate the total of the sale
total_sale = purchase_amount + total_tax

# Display the results
print("Amount of the purchase: $", purchase_amount)
print("State sales tax: $", state_tax)
print("County sales tax: $", county_tax)
print("Total sales tax: $", total_tax)
print("Total of the sale: $", total_sale)
```

When you run this program, it will ask the user to enter the amount of the purchase. After the user enters the amount, the program will calculate and display the state sales tax, county sales tax, total sales tax, and total of the sale.
