Practical Example Calculation
Scenario Context: You buy a television for $450 in a city with a state tax of 6% and a local county tax of 1.25%. What is the sales tax and total due?
Step 1: Sum the tax rates: 6% + 1.25% = 7.25% cumulative tax rate.
Step 2: Multiply Net Price by tax rate: Tax Amount = $450 × 0.0725 = $32.625 (rounds to $32.63).
Step 3: Add tax to net: Total Price = $450 + $32.63 = $482.63.
The total sales tax is $32.63, making the checkout register total $482.63.
