Hello!
<h2>Answer:</h2>
Carla will pay $300.30 for the gold ring.
<h2>Explanation:</h2>
Sales tax is added on to the total cost of the item. We need to figure out how much tax is on the ring.
To do that, we must calculate 10% (or 0.10) of $273.00.
273 × 0.10 = 27.3
Now, add the tax to the cost of the ring.
273 + 27.3 = 300.3
