To find the sales tax rate, we can use the formula:

\[ \text{Sales Tax Rate} = \frac{\text{Sales Tax}}{\text{Cost before Tax}} \times 100 \]

In this case:

  • Sales Tax = $23.40
  • Cost before Tax = $390

Now, substitute the values into the formula:

\[ \text{Sales Tax Rate} = \frac{23.40}{390} \times 100 \]

Calculating the fraction:

\[ \text{Sales Tax Rate} = 0.06 \times 100 \]

Now, calculate the percentage:

\[ \text{Sales Tax Rate} = 6% \]

Thus, the sales tax rate is 6%.
