It's hard to give you a specific number as each situation is different, but as a graphic designer myself, these are some questions I would ask to determine a number:
• How long would it take someone to recreate this from scratch from a purely production standpoint?
• How much intellectual property value is in the work?
• What can they do with these files going forward? How much potential does it have?
• Is there a previous arrangement in terms of who owns the work?
• What size of company is the client?
• How much did I bill this company for creating the original work?
• Do I hope to get future business from this client? Or am I just trying to maximize profit?
Figuring out something like this can be a little subjective, but at the end of the day, she should be charging an amount that she won't be second-guessing later, and won't offend either her own skills or the client.
Oh, and if she already gave them a number....I wouldn't go back and ask for more now. That would be in poor taste.
