conversations.value: Can you walk me through the solution of: Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples.  Barry can reach apples that are 5 feet high.  Larry is 5 feet tall, but his shoulder height is 20% less than his full height.  If Barry stands on Larry's shoulders, how high can they reach?

conversations.value: Larry's shoulder height is 20% less than 5 feet, or 0.2*5 =1 foot less than 5 feet.
  One foot less than 5 feet is 5-1=4 feet.
  If Barry stands on Larry's shoulders, they can reach 4+5=9 feet.
