Ruby offered to sell her car to John for $5000. She sent the offer by email. John sent a return email to tell Ruby he was "ok with the price" but wanted the car "cleaned and detailed if he was going to buy it." Ruby just wanted to get rid of the car so, instead, she sold it to her college roommate that afternoon. When John found out, he was upset. He told Ruby he had accepted her offer when he said he was "ok with the price" and merely asked her to wash the car and detail it before he picked it up. Turns out, the car was worth much more than Ruby was asking. Now, John is suing her because he says they had a contract.

Using IRAC, determine whether the facts above give rise to a valid contract between Ruby and John for the sale of the car. Give explanation
