**Program One: Basics**

This introduction outlines the foundational steps for programming a simple calculator focused on computing the cost of purchasing Cornish pasties, inclusive of tax.

### Program Outline:

- **Objective**: Calculate the total cost of buying Cornish pasties, including tax, and return a price before tax, subtotal, and final total.

#### Key Instructions:

1. **Functions**: 
   - You do not need to use functions or restart features for this basic program.

2. **Comments**: 
   - A minimum of three comments are required within your code for clarity.

3. **Program Requirements**:
   - Display the initial prompt: “Welcome to Axia's Cornish Pasties! Enter the number of pasties (Max 10):”
   - Calculate and display costs to three decimal places.
   - Use a tax rate of 7.75%.
   - The program should properly handle input and display results with the appropriate number of decimal places.
   - Subtotals and totals should be presented clearly.

4. **General Guidelines**:
   - Ensure all outputs are aligned neatly.
   - Only accept numeric data; handle any incorrect input gracefully.
   - Run the program only once per execution attempt, and avoid using incorrect data.

#### Visual Output Example:

- **Mockup**:
  ```
  Welcome to Axia's Cornish Pasties!
  Enter the number of pasties you wish to purchase (Max 10):
  Pasty Price: $10.00
  Tax: $0.78
  Total: $10.78
  Thanks for enjoying pasties from Cornwall!
  ```

5. **User Interface**:
   - The program must work with a variety of pasty prices and percentages, ensuring flexibility.

This foundational program provides a practical introduction to basic input handling, data processing, and presentation, setting the stage for more complex programming tasks.

Expert Solution
Step 1

Introduction of the Program:

The Python program takes the price of the pasties and tip % that you want to give from the user and then the program calculates the tax, subtotal, tip, and total and displays the output and the program checks the inputted data should be an integer.
