A sales tax is a tax paid to a governing body for the sales of certain goods and services.
Sales tax is calculated by multiplying the price of an item by the tax rate. Example: you buy a car for 30,000 dollars and pay 6% in tax.
Tax = 30,000 times 6% = 30,000 times 0.056
Tax = 30,000 times 0.06 = 1,800 dollars.
The cost of the car with tax is 30,000 + 1800 = 31,800 dollars
