🧠 The Math Behind Sales Tax
Sales tax is calculated using the formula:
Sales Tax = Purchase Amount × (Tax Rate ÷ 100)
Total Price = Purchase Amount + Sales Tax
For example:
Purchase Amount: $100
Tax Rate: 8.25%
Sales Tax = $100 × (8.25 ÷ 100) = $8.25
Total = $108.25
You can also reverse-calculate to determine how much tax is included in a final price.

Example 2: Reverse Calculation
| Total Price | Tax Rate | Base Price | Tax Amount | 
|---|---|---|---|
