Best Answer

Your question is vague, but we can assume you're talking about adding sales tax to an item that is sold at retail. If the sales tax is 5 percent, multiply the item's tag price by 1.05, which gives you the total price. For example, if a sweater is 20 bucks, multiply that by 1.05, which gives you 21 dollars. Some people calculate the tax and then add it to the price. Five percent of 20 bucks is one dollar, so 20 plus one is 21.

First you calculate the amount of the tax on the item. Then you add together the original cost of the item and the tax.

the way I learned was to add the percent of tax on to 100% and multiply whatever your taxing by that. for example: 6% tax on a $7 item 106% times $7.

The easiest way to understand the answer is to turn it around. If you wanted to calculate the item price plus tax, you would multiply the item price by 1.073. So, to back up to the item price from the item price plus tax, divide the item price plus tax by 1.073. $20.00 / 1.073 = item price before sales tax.

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.

The total tax is $1.06 and the total price with tax is $14.37

Multiply the pre-tax price by 1.065

You simply multiply the tax rate with the item's original cost and divide by hundred, to get the tax. Then you add that to the original cost, to get the total cost. In Java you use + to add, * to multiply, and / to divide.

Multiply the pre-tax cost by 1.0775.

You multiply 102.00 by 1.0775

686.00 x .0685 = 47.402 686 + 47.40 = 733.40

Add the 2 amounts together or take the item to the check out counter and they will tell you the cost of the item including the tax when they finished and ready for you to pay for it.

No, so if you try to buy something, the item will always have tax. For example: I want an item that cost $5.76. And I give the clerk $16.96. So I told you that an item will always have tax right, so lets say the tax was $0.57. So we add the price of the item with the tax and we get $6.33. Now lets subtract $16.96 minus $6.33 and we get $10.63. So $10.63 is our change.
