Change for a dollar?
Divide $542 (in whole $ increments) into a number of bags so that I can ask for any amount between $1 and $542, and you can give me the proper amount by giving me a certain number of these bags without opening them. What is the minimum number of bags you will require?

Thta's close, anonymous... You don't have $512 for the last bag:ReplyDelete
You divide $542 (in whole $ increments) into 10 bags as follows:
1, 2, 4, 8, 16, ... , 256, 31.
