QUESTION 3 [CLO 3] On January 10, 2020, Richard places an ad in the newspaper which states: "Looking for 2005 CRV. Prepared to purchase for $5. Please contact." On January 11, 2020, Abby responds by letter stating: "I accept. Come and collect the car." The letter never gets to its destination. On January 12, 2020, Johnson calls Richard and explains to him that he is selling the vehicle he wants but it is for $10.
