Use the data in tblReservations and tblRoomCharges to create a
query that calculates the attendants’ gratuity on a room service
order (18%) or spa treatment (25%). Your query results should
display ReservationID, CheckInDate, ChargeCategory, ChargeAmount,
and a calculated field named Gratuity in that
order. If the ChargeCategory is not a spa treatment or room
service, a zero should be displayed in the field.
