For Sale: Stolen black diamond earrings, rare, beautiful, retail value: $600, Asking price is $10. First come, first served. Contact Tate at 555-5599.

Kate was the first to contact Tate, and show up to buy the earrings. Kate tendered $10 to Tate, who gave her the earrings.

Is there an enforceable contract between Tate and Kate? Fully explain your decision and your reasoning.

(Remember that there is no enforceable contract unless action is necessary to complete it, making it a unilateral contract offer)
