Worked Example

Let's calculate the sales tax for a $25,000 vehicle purchased in Davidson County:

Vehicle Price = $25,000

Sales Tax Rate = 7.00%

Total Sales Tax = $25,000 × (7.00 / 100) = $1,750

Total Price = $25,000 + $1,750 = $26,750

So, the total sales tax would be $1,750, and the total price you would pay would be $26,750.
