Here is a puzzle that I have been having difficulty with. Let me know what you think.
Your friend and you are in a standard American mall and see a vending machine. Your friend pulls out a crisp $1 bill to buy a 95 cent candy bar, but then realizes that the machine takes exact change only. Your friend turns to you and asks if you could break a dollar. You reach into your pocket and fish out 6 coins, which add up to $1.15 saying, "Well, with this amount I should be able to break a bill ... but it appears that I cannot!" Upon further examination, you see that you cannot give change for a 50 cent piece, a quarter, a dime, or even a nickel with the 6 coins you have.
Frusturated, your friend asks you to just buy him the candy bar and you realize... you cannot buy the 95 cent candy bar.
What are the 6 coins that you have?
My attempt is in the spoiler. Only read the spoiler if you attempted the puzzle by yourself to garuntee a fresh mind!
