For example

Amounts
$343,200 $385,000

Increase
41,800

percentage
12.2%

how do I determine that 41,800 is a 12.2% increase from 343,200 to 385,000?

I know there is a formula for dertermining that the change is 12.2% but I just can't remember it.

I pulled this off the web:

The bottom line is that logic alone can tell us nothing new about the real world. Ditto for mathematics, as Albert Einstein observed: "Insofar as mathematics is exact, it does not apply to reality; and insofar as mathematics applies to reality, it is not exact."

"Logic and math do not, and cannot, generate new truths about nature. They only expose and reformulate the truths contained in our models, theories and laws. The conclusions aren't absolute truths, but 'proximate' truths, since the raw materials upon which theories are built are based upon imperfect measurements and observations of nature."
