Extra credit question for math class...

3 men go to a hotel room for a night. The manager charged them $30, therefore they split the bill “$10” each.
The manager later realized that he made a mistake and the total should’ve been $25, not $30...
The manager tells the bell boy to return the $5 to the 3 men, but the bellboy cheats and pockets $2 and only returned $3...
now each guy did not pay $10... they each payed $9, because they each got $1 back.

Each guy payed $9 = $27
Plus $2 in bellboys pocket

Total is $29

Where is the missing dollar?

Respuesta :

they paid 30, 10 + 10 + 10.

the manager refunded them 5, 30 - 5 = 25.

the bellboy took 2, gave them 3 only.

since the bellboy gave only 3 to friends, then they paid 10 + 10 +10 - 3 = 27, if we include the 2 the bellboy kept, then that makes it 27 - 2 = 25.

we're not adding the $2 kept by the bellboy, we're subtracting it from the $27.
