I have made a price spreadsheet that we use in the office, now my boss wants
me change all the prices by adding 10% to all numbers. When I set up the
spreadsheet, I just typed in the numbers, I did not use any formulas. I
cannot figure out how to do this, and I really do not want to change each
cell one by one.
HELP!!
