This is in Microsoft Access

Use the data in tblReservations and tblGuests to create a query that calculates the guest’s total room charges. Your query results should display GuestFirstName, GuestLastName, ReservationID, CheckInDate, NightsStay, RoomRate, DiscountType, and a calculated field named TotalRoomCharges in that order. Subtract any discount from the total charges. In addition to the discount data in the database, AARP and AAA members receive a 10% discount. Military personnel receive a 20% discount. Guests without a discount should still have their total room charges calculated.
