Hi there!

I am quite stuck with this problem, and I wasn't too sure which category it belonged under. So here goes!

Let's say a robber has stolen money from a bank. It may have consisted of $50 and $100 bills or only $100 bills, or some combination of $5,$10,$20,$50 and $100 bills. How would I use a general method for figuring out whether or not a person (robber) could carry ANY amount of money, using ANY combination of bills.

I understand the situation - I am just unsure as to preparng a general method or formula.

Any suggestions would be much appreciated!
