Question

a new shirt costs $34.99 and the sales tax is $2.10, the sales tax rate is
4 percent.
2 percent.
8 percent.
6 percent.

Explanation:

Step1: Recall the sales tax formula

The formula for sales tax is \( \text{Tax} = \text{Cost} \times \text{Tax Rate} \), so we can rearrange it to find the tax rate: \( \text{Tax Rate} = \frac{\text{Tax}}{\text{Cost}} \times 100\% \).

Step2: Substitute the given values

We know the cost is \( \$34.99 \) (approximate to \( \$35 \) for easier calculation, but we can use the exact value) and the tax is \( \$2.10 \). So we calculate \( \frac{2.10}{34.99} \times 100\% \). Let's do the division: \( 2.10 \div 34.99 \approx 0.06 \), then multiply by 100% to get \( 6\% \).

Answer:

6 percent
