The first thing you should do in this case is calculate the tax percentage. We then have to apply the following rule of three: $ 63 ----> 100% 6 $ ------> x Clearing x we have: x = (6/63) * (100) x = 9.523809524% Therefore the taxes of the second item will be Tax = (9.523809524 / 100) * 210 Tax = 20 $ Answer: The sales tax on the second item is: Tax = 20 $
