![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F93423dcf-8fa5-41fe-8782-938bb8d00d1a%2F14e42c38-fe8d-4404-a2af-eda7d609fbba%2F0yj57jg_processed.png&w=3840&q=75)
