Okay. So to find the amount of sales tax, we have to first subtract the text book cost from the total. 113.94 - 108 = 5.94. That’s $5.94 in taxes. To find the percentage, we have to do the amount in taxes divided by the cost of the item, in this case, the textbook. 5.94 / 108 is 0.055. Multiply 0.055 by 100 in order to get the percentage. When you do that, you get 5.5%. Matthew was charged 5.5% in sales tax.
