Step-by-step explanation:
A sales tax is a tax imposed on business transactions, especially the sale of goods and services. It is a tax assessed on an item bought in a store, calculated as a percentage of the purchase price. Sales taxes are collected by the seller at the time of sale.
For example, if the sales tax rate is 10% and you buy an item that costs $100, you would need to pay an additional $10 in sales tax, bringing the total cost of the item to $110.
It is important to note that sales taxes vary among jurisdictions and may exempt certain goods or services from taxation.
