In Excel, adding percentages, needing to correct, and having to get back to the original amount. Can I do this?

A friend added 8% to a column of random numbers (amounts) in Excel. The next day, he found out that was supposed to add a different percentage. Looking at this row of numbers, how can he get back to his original amount? He can't just subtract 8%, because that 8% will be larger than the original.
There is no backup, and he saved and exited a day previous.
I suspect he's screwed, am I right?
