Answer

Explanation:

Step1: Calculate the sales - tax amount

The total amount paid is $57.50 and the price of the blazer is $52.85. So the sales - tax amount $t$ is $t = 57.50−52.85=4.65$.

Step2: Calculate the sales - tax rate

The sales - tax rate $r$ is calculated by the formula $r=\frac{t}{p}\times100%$, where $t$ is the tax amount and $p$ is the price of the item before tax. Substitute $t = 4.65$ and $p = 52.85$ into the formula: $r=\frac{4.65}{52.85}\times100%\approx8.79%$.

Answer:

C. 8.79%
