On March 1, A sends a letter to B in which he offers to sell B a car for $1,000. On March 2, B mails A a letter accepting the offer. The letter, although properly addressed, was delivered to the wrong recipient, and A did not receive it until March 30.By that time, A had concluded that B was not interested in the offer and had already sold the car to someone else.When B finds out that the car is no longer available, he is furious.He calls A on the phone and says "How could you sell my car?We had a contract!"Is B correct that A has breached a contract with B?
