Final answer:
The subject of this question is Mathematics and the grade level is High School. Given that three stores have the identical price of $300 and each store charges 18 percent sales tax, we can calculate the total price of the Samsung Galaxy smartwatch in each store by adding the sales tax to the original price.
Step-by-step explanation:
The subject of this question is Mathematics and the grade level is High School.
Given that three stores have the identical price of $300 and each store charges 18 percent sales tax, we can calculate the total price of the Samsung Galaxy smartwatch in each store by adding the sales tax to the original price. Using the formula:
Total Price = Original Price + (Sales Tax Percentage * Original Price)
For example, the total price at one store would be $300 + (0.18 * $300) = $354.
