question: Gunter is trying to count the jelly beans in a jar. He asks his friends how many they think are in the jar. One says 80. Another says 20 more than half the first one. A third says 25% more than the first one. What is their average guess?
answer: The second person guessed 60 because 20 + (80/2)= <<20+(80/2)=60>>60
  The second guessed 100 because 80 x 1.25 = <<80*1.25=100>>100
  The total amount guessed is 240 because 80 + 60 + 100 = <<80+60+100=240>>240
  The average amount guessed is 80 because 240 / 3 = <<240/3=80>>80
  #### 80
