Answer: The sales tax was 9.5%
Step-by-step explanation: The sales tax of an item is usually a percentage of that item's cost. Thus, in order to determine the sales tax percentage, we can divide the cost of the tax by the original cost of the item. The sales tax is 570, and the original cost of the guitar is 6000.
First, we divide 570 by 6000. [tex]\frac{570}{6000}[/tex] yields 0.095. In order to convert that to a percentage, we simply multiply the quotient by 100 and add a percentage sign. 100 x 0.095 yields 9.5 Thus, the sales tax on the vintage guitar was 9.5%.
