Example: I want to add 10% to the value of each number in rows A1 through to
A500. Each cell contains a different value. (ie. 5, 6.75, 3.15 etc). I know
how to add a percentage to a single cell but is there a way you can add a set
percentage (10%)to several hundred cells at once without having to do them
all individually? Your help is very much appreciated.
