Answer:
$117.14
Step-by-step explanation:
A<em> "sales tax"</em> refers to a specific amount of money <em>(according to its percentage</em>) that you need to pay other than the price of the good stated.
So, if the price of the smart watch is $109.99 and the sales tax is 6.5%, you have to know much is 6.5% of $109.99. This can be computed by using the <em>multiplication operation.</em>
109.99 x 6.5% (0.065) = $7.15 (this is the sales tax)
In order to know the total cost of the smart watch, you have to add the sales tax to the price of the smart watch.
$109.99 + $7.15 = $117.14
The total cost of the smart watch is $117.14
