HELPPPPP!!!!!!!

Blake offers to sell to Poe a copy of Lord Byron’s first edition of poetry for $22,000 and specifies the acceptance has to be in writing, accompanied by a check for the required amount, and delivered by certified mail. Poe follows the offer’s instructions exactly and mails the certified letter at 3 p.m. on April 1. However, at 9 a.m. on April 1, Blake accepted an offer of $30,000 for the edition. He then mailed a revocation of his offer to Poe at 1 p.m. the same day. The revocation arrived at Poe’s address at noon on April 2. Which contract will be upheld by the courts? Provide a CLEAR answer to the question.
