---

## Initial Table State

## Applying Discounts

1. **Discount Criteria**:  

   If the quantity is **greater than or equal to 20**, we mark "Y" for a discount, otherwise "N":

2. **Discount Calculation**:  

   If a discount is applied ("Y"), the total amount is multiplied by **0.95**:

  Using **VLOOKUP**, we retrieve company names:

## PivotTable Analysis

Finally, we use **PivotTable** to analyze the data:

1. **Total Sales by Chair Models by Month**:
