how do you add tax to something with a caculator if its .10 cents for each dollar?

Answer 1

If calculator does not offer option of presetting ten percent, than it would be two steps: Multiply amount by 10% and add answer to original amount,

Answer 2

In many calculators you type DOLLARS * 10% +

Another simple way without the % key is to just add 1 to the percent as a decimal and multiply by it.

For example if the tax is 10% you just multiply by 1.10 to get the answer.

Answer 3

10 cents on the dollar is 10%. Multiply the sale price by .10 to get the sales tax. Multiply the sale price by 1.10 to get the sale price with the tax added.

Answer 4

when you get your total, multiply time 1.1
You use 1.1 because the 1.0 give you your total and the .1 will add the 10% tax to it.

If you multiply time .1, then you will need to add that back to your total so it's easier to multiply times 1.1! Good Luck! God Bless!

Answer 5

You really shouldn't need a calculator for such an easy equation.

Answer 6

whatever your amount times 0.1 percent ie :0.1%
