A man walks into a hardware store and picks up an item. He asks the clerk “How much for 1?” The clerk says “Fifty cents”. “How about for 36?” asks the man. “That would be $1.” says the clerk. “Well then, how much for 105?” asks the man. “That would cost $1.50.” says the clerk. What was the man trying to buy?
