Final answer:
The formula for general sales tax is Total Sales multiplied by the sales tax rate (A. Total Sales × ts). To determine the total amount after tax, add the sales tax to the item's original price.
Step-by-step explanation:
The formula for calculating general sales tax on consumption at a rate ts is A. Total Sales × ts. This formula represents the amount of sales tax based on the sales price of the goods or services. To calculate the total cost including sales tax, you would take the original price and add the calculated sales tax to it.
For example, if you have an item that costs $65.00 and the sales tax rate is 5%, you would first convert the percentage to a decimal (0.05), and then multiply it by the price of the item: $65.00 × 0.05 = $3.25. This $3.25 represents the sales tax, which, when added to the original price, gives you the total amount due.
