An item costs $380 before tax and the sales tax is $15.20 find the sales tax rate write your answer as a percentage

Respuesta :

The sales tax is 4%.

To find the sales tax use the equation to solve for x and determine what percentage 15.20 is of 380.

$380 * x = $15.20

X = 15.2/380

X = .04

Convert .04 into a percentage by multiplying by 100, which equals 4%.
