Final answer:
Individuals living in the same state but different counties can face different general sales tax rates due to the addition of local sales taxes by municipalities. These variations in sales tax rates are often used to fund local public services and infrastructure.
Step-by-step explanation:
Two persons living in the same state but in different counties may indeed be subject to different general sales tax rates. While most states impose a base sales tax, local jurisdictions, such as cities and counties, have the authority to add additional sales taxes on top of the state rate. This results in varying sales tax rates within a single state.
For example, in a state like New York, the state sales tax might be a certain percentage, but each county can impose an additional sales tax rate. Therefore, someone living in one county might pay a different total sales tax rate on their purchases than someone in a neighboring county.
