help find my missing $1, page-2

    They originally paid $10 each = $30

    The hotel refunded $5, leaving $25 for the hotel.

    They got refunded $1 each = $3
    This leaves $2 for the porter. Total $5. No missing money here.

    $30 originally paid -$3 refund = $27 total paid. $27 / 3 = $9.00 each paid. No missing money here either.
