George, Paula, and Della were having lunch together. Paula mentioned that she was interested in buying a bicycle. Della stated: "I have a bicycle I would be willing to sell you, but I am not sure on what would be a good price. George stated: "I've seen your bicycle, Della, and I think it is worth $100." Paula and Della immediately stated that $100 was a proper price. Have Paula and Della entered into a contract? 1)Yes, because there was agreement to the price term suggested by George. 2)Yes, provided that $100 is indeed a fair price. 3)No, because there was no mutual assent between Paula and Della since they did not suggest the price. 4)No, because it is not possible to specifically identify the offer and acceptance
