If the tax is 10 percent and the price of the item is $1.00 then you simply calculate 10% of 1.0. = 10 cents and add it to the original price.You would charge the person $1.10 (including tax).The simple way to calculate the final price mathematically is to express the percent as a decimal and add 1 to it. Then multiply the price by this number.I.e If the tax is 5.6% you would express this a 0.056 + 1 = 1.056 and multiple the pre tax price by this number.
