Calculate the sales price of an item where sales tax was included in the price by dividing the price the customer paid by 1.0 plus the sales tax rate. For example, if the tax rate is 7.0 percent and you sold an item for $100, sales tax included, divide the $100 by 1.07. The result will be a price of $93.46 and sales tax of $6.54.
7 divided by 1.12 is 6.25
Its not 12% of 7 if you want 12% of 7 then you need to uncheck tax included.
