A patient is at your store buying a glucose monitor. the item sells for $69.99. After tax their total is $75.94. what is the tax rate?

This is how you determine that:
75.94 ÷ 69.99 = 1.085

Then, whatever is after the decimal is your percentage. In this case it's 8.5%.

To check your answer, multiply the sale price by that rate and add it all up.

That would look like this :
69.99 X .085 = 5.95 (tax)

69.99 (Price)
+5.95 (Tax)
75.94 (Total)


This is also explained on the Percentage Math Page, about half way down the page. Look for "Markup Percentage Math".
