Solution Explanation:
#### Step 1: Verify the Calculation for Each Item
We need to check if the total for each item is correctly calculated using the formula:
\[
\text{Total} = \text{Quantity} \times \text{Unit Price}
\]
1.
Mouse:
- Quantity: 10
- Unit Price: 500
- Total: \( 10 \times 500 = 5000.00 \)
- The calculation is correct.
2.
Keyboard:
- Quantity: 15
- Unit Price: 1050
- Total: \( 15 \times 1050 = 15750.00 \)
- The calculation is correct.
#### Step 2: Verify the Total Amount
The total amount is the sum of the totals for all items:
\[
\text{Total Amount} = \text{Total for Mouse} + \text{Total for Keyboard}
\]
\[
\text{Total Amount} = 5000.00 + 15750.00 = 20750.00
\]
- The total amount is correctly calculated.
#### Step 3: Check for Consistency
- The customer name and invoice date are filled in correctly.
- The "Add Item" button allows adding more items if needed.
- The "Generate Invoice" and "Print Invoice" buttons are present for further actions.
#### Step 4: Final Verification
All calculations are consistent and accurate:
- Individual item totals are correct.
- The overall total amount matches the sum of individual item totals.
---
Conclusion:
The billing invoice form is correctly filled out with accurate calculations. The total amount of
20750.00 is verified as correct.
Final Answer:
\[
\boxed{20750.00}
\]
