A $34 badminton set costs $35.70 after sales tax is figured in. What is the sales tax percentage?

Write your answer using a percent sign (%).

The sales tax amount is $35.70 - $34 = $1.70.

To find the sales tax percentage, we divide the sales tax amount by the original price of the badminton set: $1.70 / $34 = 0.05.
Finally, we convert the decimal to a percentage by multiplying by 100: 0.05 * 100 = 5%.
Therefore, the sales tax percentage is 5%.
