Question
**Order Total Calculation Example**

In this example, we aim to display all orders with their calculated total amounts. For instance, if an order includes the purchase of 1 iPhone and 3 iPads, the total amount for that order would be calculated using the formula:

\[ \text{Total} = 1 \times \text{iPhone\_price} + 3 \times \text{iPad\_price} \]

### Example Output:

The table below shows a sample output of orders with their respective total amounts.

| **order_id** | **total_amount** |
|--------------|------------------|
| 1            | 7.5              |
| 2            | 8.5              |
| 3            | 10               |

This table lists:
- **order_id**: A unique identifier for each order.
- **total_amount**: The calculated total cost for the respective order.

This example serves as a guideline for displaying order totals based on product prices and quantities.
