Is it possible to update or change the values in a range of cells by a
certain percentage? What I'm trying to do is apply a 10% increase to a column
of prices (several hundred cells long) without doing it manually one by one
or creating a new column (B) that references the values in the first column
(A) and then manipulates the values by X%.

Basically, I'm supposed to update the price list without changing it's
present format. I expect to need to do this again in the future several times
and it would be wonderful if there was some way to do it quickly and easily.

Thanks for any ideas!!
