I got this problem from TinTin (aka Jamjam) hehe (she hates it when I call her jamjam).

Divide $114 (in whole $ increments) into a number of bags so that I can ask for any amount between $1 and $114, 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?

I'm gonna need seven bags.

Yes. And the amount in each of the seven bags should be 1, 2, 4, 8, 16, 32, and 51.
