An item cost $4 before tax and $4.32 after sales tax. What is the sales tax rate?
erma4kov [3.2K]

The sales tax rate of an item that costs $4 is 8%

<h2>Explanation:</h2>
  • An item costs $4 before tax
  • The same item costs $4.32 after sales tax.

So the tax rate can be calculated as:

Tax rate = $4.32 - $4 = $0.32

Next, you must divide the tax rate by the original price in order to get the sales tax rate:

Sales tax rate = $0.32/4$ = 0.08

In percentage:

Sales tax rate % = 0.08x100% = 8%
