What best describes the basis of sales tax?

Sales tax is a consumption tax levied on the sale of goods and services, typically calculated as a percentage of the purchase price. It is collected by retailers at the point of sale and remitted to the government. The basis of sales tax is the final sale price paid by the consumer, excluding certain exemptions like food or medicine, depending on the jurisdiction. This tax is used to generate revenue for local, state, and sometimes federal governments.
