Question: how much tax is taken out of 900 dollars?
Answer: A tax of 7.5 percent was added to the product to make it equal to 967.5. So, divide 7.5 by 100 to get 0.075. Divide the final amount by the value above to find the original amount before the tax was added. In this example: 967.5 / 1.075 = 900.
