Jonny,

Enter 0.20 in some empty cell and copy that. Then select the
cells you wish to change. Go to the Edit menu, choose Paste
Special, and use the Multiply option.

Hello,

I am a novice Excel user trying to tackle the following
problem - I
have a spreadsheet with about 1500 rows of prices all situated
in one
column. I would like to apply a certain markup percentage to
each item.
Is there a formula or some other technique I can use to apply
this
arbitrary percent (say 20%) to the price column without having
to do it
line by line?

Thanks,

Jonny
