The Jelly Bean Problem

 The local high school was trying to raise money for a class trip by having students pay $1 to guess the number of jellybeans in a jar.  Adam guessed there were forty-three, Bill guessed thirty-four, and Carl guessed forty-one.  One person was off by six, another was off by three, and another was off by one.  How many jellybeans were in the jar?
