To take a percentage of a price, multiply the price by the decimal equivalent of the percentage, which is the percentage divided by 100. 25 percent of $15.00 = 15 x 0.25 = $3.75 To add a percentage to a price, you can either add that number to the original price ($15.00 + $3.75 = $18.75) or multiply the original price by the decimal equivalent of 100 percent plus the discount. (15 x 1.25 = $18.75)
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.
If the original price was $42, a 50% markup would add another $21 to make the price be $63.
