This is my thing if I take $104. And I need to add a 10% increase how would I learn to add that.

25000 + or *17.5%

How do you add $7.99 + .75 cent + 5 percent

$20 plus 500%

174,000. Divided by 1/3

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

Do what the first guy did say you want to add 15% to a 100 dollars 100 divided by 100 get 1 x 15 get 15 add to 100 115 .= to

DO WHAT THE FIRST GUY DID

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

Example

$100 + 8% of $100

= $100*(1.08) = $108.

Example

8% of $100 = $8.

$100 + $8 = $108

Umm you do what ever.
