сдача 101

[anspa]

Арик прислал перед концом дня в пятницу: -

"Three guys rent a room for $30 and each pays $10. The receptionist realizes he made a mistake and sends back to the room $5 with the bellboy.
The bellboy doesn’t know how to divide 5 by 3, so he keeps $2 and gives $1 to each guy, therefore each guy only paid $9. Nine times three is 27, plus 2 from the bellboy is 29.
Where is a dollar?"

по-моему я что-то такое уже решал.

25$ + 2$ is what they've paid or 9 times 3
Oldie but goodie

Right, perception of counting the refund as a charge.

$27 - $2 = $25 that they paid to the landlord after bellboy's $2 tip.

Вот так же наши депутаты в государственном бюджете пытаются разобраться.
