Adding a percentage to a dollar is like adding a percentage to anything. Say you had a hundred pounds, you divide the amount by one hundred (the maximum standard percentage) and then you decide how much you want to add, say twenty five percent. So one hundred divided by one hundred is one and then twenty five times that is twenty five, add it together and you have one hundred and twenty five dollars.

If we tackle a more difficult one. What if we have the figure of three hundred and twenty five dollars seventy, plus twenty two percent. So:

Step one: divide amount by one hundred, so it's 325.70 divided by one hundred. The easy way to do this is to move the decimal point two places to the left, so it's 3.2570.

Next multiply that by 22. A simple sum 3.2570 X 22 = 71.654

Now add 325.70 to 71.654 =$397.354

I find it easiest to multiply by (1+[the percentage expressed as a decimal]), particularly if I'm using a calculator.

Example
$100 + 8% of $100
  = $100*(1.08) = $108.

You could figure the percentage, then add. I usually do it this way for approximating sales tax and figuring tips.

Example
8% of $100 = $8.
$100 + $8 = $108
