Caryn offered to tutor Dottie in business law for six hours on the day before the final exam in return for $100. Dottie responded, “Let me think about it for a day, okay?” Two hours later Jim offered Caryn $150 to tutor him on the day before the final and she accepted. Dottie called Caryn an hour later and said, “I accept.” Caryn said, “I’m sorry but I’ve already agreed to tutor Jim that day so I can’t tutor you.” Was there a contract between Caryn and Dottie?
