Editor's Note: Another re-run. The names have been changed ... etc.
Three travelling orienteers decide to participate in an orienteering competition while on vacation far from their native New Brunswick. At the registration table, they each pay their meet fee of $10.00, collect their maps and head off to sharpen their spikes, or apply some more flux to their compass needle, or do whatever orienteers do just before their start time.
Back at the registration table, the late entry crowds have subsided and the meet director realizes that he has charged the three visiting orienteers the wrong amount. In fact, a discount of $5.00 is commonly applied to the combined meet fees of at least three out-of-town orienteers when competing in local meets. The meet director commissions the services of a passerby and asks this person to deliver $5.00 to the three out-of-town entrants over there in the funny blue-white-and-gold suits.
While walking over to our heroes, the delivery-type-person, obviously not an orienteer, decides to her/himself that since $5.00 is not equally divisible by three, s/he would simply pocket $2.00 and return $1.00 to each of the three New Brunswick bumpkins. And s/he does.
Now, each of the three New Brunswick orienteers has paid $9.00, thereby totalling $27.00. That $27.00 plus the $2.00 in the delivery-person's pocket total $29.00. What happened to the other dollar?
