0.72 cents because 9 plus 0.72 is 9.72

justicehall2002

If the cost is $9.72 but what you bought was only $9, you paid $0.72 in tax for each $9 spent. To find the amount of tax per dollar, or the sales tax rate, divide 0.72 by 9, or 0.08. That means that there is a tax of 8% per dollar

Hope this helps!
