Final answer:
The question is about calculating the total cost of a watch after adding a 6% sales tax to its original price of $8,000.
Step-by-step explanation:
The subject of this question is Mathematics, and it is typically at the high school level. The question involves calculating the sales tax on a watch with a retail price of $8,000 and a sales tax rate of 6%. To determine the total cost of the watch including sales tax, the formula used is: Amount of sales tax = price × rate of sales tax. In this example, the amount of sales tax would be $8,000 × 0.06, which equals $480. The total cost, therefore, would be the original price of the watch plus the sales tax; $8,000 + $480, totaling to $8,480.
