1. What is a Restaurant Tax Calculator?

Definition: This calculator computes the tax amount and total bill based on the pre-tax amount and local tax rate.

Purpose: It helps diners and restaurant staff quickly determine how much tax will be added to a food bill.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tax amount (USD)
• \( B \) — Bill amount before tax (USD)
• \( r \) — Tax rate (decimal, e.g., 0.075 for 7.5%)

Total Amount: \( \text{Total} = B + T \)
