2. I don't understand. It looks like it adds up to more than \$1000. How much would be in each bag?

It is well known that the powers of 2 can be used to represent every number from 1 on up. From 1, 2, 4, 8, 16, 32, etc., 1 - 1, 2 = 2, 3 = 4 - 1, 5 = 1 + 4, 6 = 2 + 4, 7 = 1 + 2 + 4, and so on. Therefore, filling each bag with \$1.00 bills of quantities 1, 2, 4, 8, 16, 32, 64, 128, 256 and 489 can be used to fill the bags and be able to give any amount requested without opening the bags.

Bag 1 = 1
Bag 2 = 2
Bag 1 + bag 2 = 3
Bag 3 = 4
Bag 1 + bag 3 = 5
Bag 2 + bag 3 = 6
Bag 1 + bags 2 and 3 = 7
Bag 4 = 8
Bag 1 + bag 4 = 9 and so on.
Bag 1 plus bag
