Yokel, a grower of soybeans, had sold soybeans to Campbell Grain and Seed Company and other grain companies in the past. Campbell entered into an oral contract with Yokel to purchase soybeans from him. Promptly after entering into the oral contract, Campbell signed and mailed to Yokel a written confirmation of the oral agreement. Yokel received the written confirmation but did not sign it or object to its content. Campbell now brings this action against Yokel for breach of contract upon Yokel's failure to deliver the soybeans. Is the agreement binding? Explain.
