Final answer:
Emma paid $27.97 in sales tax for her new tablet, which is approximately 8.5% of the tablet's original cost of $329.
Step-by-step explanation:
Emma needs to determine the amount of sales tax she paid on the purchase of her new tablet. The tablet cost $329 and her total at checkout was $356.97.
To calculate the sales tax paid, we need to subtract the original cost of the tablet from the total cost at checkout. So, $356.97 - $329 = $27.97. This is the amount of tax sales Emma paid.
Now, to find the sales tax rate, we take the sales tax amount ($27.97) and divide it by the original price of the tablet ($329). This gives us approximately 0.084988, which, when converted into a percentage is roughly 8.5%.
Therefore, Emma paid around 8.5% in sales tax.
