Sierra Pacific Industries purchased various areas of timber and six other pieces of real property

Sierra Pacific Industries purchased various areas of timber and six other pieces of real property, including a ten-acre parcel on which five duplexes and two single-family units were located. Sierra Pacific requested the assistance of Joseph Carter, a licensed real estate broker, in selling the no timberland properties. It commissioned him to sell the property for an asking price of $850,000, of which Sierra Pacific would receive $800,000 and Carter would receive $50,000 as a commission. Unable to find a prospective buyer, Carter finally sold the property to his daughter and son-in-law for $850,000 and retained the $50,000 commission without informing Sierra Pacific of his relationship to the buyers. After learning of these facts, Sierra Pacific brought an action against Carter. To what relief, if any, is Sierra Pacific entitled?
