Judy uses a calculator to figure out the total cost of a $16 frying pan. Including sales tax, the total is $16.48. What is the sales tax percentage?

To find the sales tax percentage, we first need to determine the amount of sales tax.

Sales tax = Total cost - Original cost
Sales tax = $16.48 - $16
Sales tax = $0.48

Now, to find the sales tax percentage, we use the formula:

Sales tax percentage = (Sales tax / Original cost) * 100%
Sales tax percentage = ($0.48 / $16) * 100%
Sales tax percentage = 0.03 * 100%
Sales tax percentage = 3%

Therefore, the sales tax percentage is 3%.
