Lydia pays $3 sales tax on a $50 purchase. Find the sales tax rate in her state.

100 * (3/50) = ________ %

3/50 = .06 = 6%

200

To find the sales tax rate, we need to calculate the percentage of the sales tax compared to the purchase amount.

The sales tax rate can be calculated using the following formula:

Sales Tax Rate = (Sales Tax Amount / Purchase Amount) * 100

In this case, Lydia paid $3 in sales tax on a $50 purchase. Substituting these values into the formula:

Sales Tax Rate = (3 / 50) * 100 = 6%

Therefore, the sales tax rate in Lydia's state is 6%.
