Question 45632: Three guys split a hotel room for $30.00. Each paid $10.00. Later, the bell boy arrives at their room. He tells them that the hotel room only costs $25.00, so he gives them $5.00. They enjoy this news so much that they pay him $2.00 for his services and split the remaining $3.00 amongst themselves.
If they all spent nine dollars = $27.00 in all as well as the $2.00 for the bellboy: $27 + $2 = $29 where did the other dollar go?
