To find tax- you would multiply the tax rate by the amount you would own to get the amount of tax. If tax was 7% and you owed $15.23 (Just came up with a random amount) Then you would multiply $15.23 by .07 and you would get $1.0661 so that would round to $1.07. With tips you would do the same thing if you wanted to leave a 15% tip then you would multiply the amount by .15. And with discounts-if you have a 25% discount on a $30 sweater then you would multiply $30 by .25 and then subtract that from $30

How do you add tax to a price?
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.
