Answer

Explanation:

Step1: Recall sales - tax rate formula

The formula for the sales - tax rate $r$ is $r=\frac{\text{Sales Tax}}{\text{Price before tax}}\times100%$.

Step2: Substitute given values

We are given that the sales tax is $$24.80$ and the price before tax is $$310$. So, $r = \frac{24.80}{310}\times100%$. First, calculate $\frac{24.80}{310}=0.08$. Then, $0.08\times100% = 8%$.

Answer:

$8%$
