Question 17540: I'm stuck on this word problem. A person has $1,000 and he needs to divide it into 10 envelopes so that any amount, from $1 to $1,000, can be given out by using one or a combination of 2 or more of the envelopes. Two envelopes can contain the same amount. I know you need have the smaller numbers, 1 through 9, so I have picked 1, 2, 3 and 4 for those. I also think you need $10 in one envelope and $20 in another, plus a $100 envelope and a $500 envelope. I have solved this using 12 envelopes, but not 10. Is there a formula or table I should be using to solve this? I really need your help! How does this work?
