Three friends (say - andy, andrew, and paul) decide to go out on a road trip. They stop on their way to a motel. The Three friends ask the guy behind the counter (say - devin), for the rate for one room. Devin, confused about the regular rate policy, asks them to give $10 each. Making the total = $30 and the regular price being $25 for three people for one room. The three friends accept the rate and proceed to their room. Few hours later, the owner of the returns and asks the newly hired Devin for the recent records. Devin tells his boss the truth about the three friends (how he took $30 instead of $25 from them). The boss scolds Devin and tells him to go return the $5 back to the three gentlemen. Devin, again, confused about the $5 split between three men, puts $2 in his pocket and returns $1 each to three men, apologizes and leaves. Now if you count these numbers, on would say each of the three friends paid $9 each with makes 3*9 = $27 and two dollars in Devin’s pocket, making the total = 29. Where did $1 go?
