Answer:
The sales tax rate is 6%
Explanation:
To determine the sales tax rate, you can first calculate the amount of sales tax paid on the purchase by subtracting the cost of the pencils from the total cost: $8.48 - $8.00 = $0.48.
Then, you can divide the amount of sales tax paid by the cost of the pencils to find the sales tax rate: $0.48 / $8.00 = 0.06, or 6%.
So, in this case, the sales tax rate is 6%.
