Belinda offers to pay Cindy $7,500 if Cindy promises never to wear a red dress again while employed as her secretary. Further, Belinda stipulates that to accept this offer Cindy must wear a very unflattering I love Hippopotamus dress to the companys black-tie event later in the month. Cindy immediately ceases wearing red dresses in the office. While Cindy thinks Belinda is ridiculous, $7,500 is a lot of money and worth not wearing red dresses. On the night of the companys black-tie event, Cindy wears a beautiful black cocktail dress. Cindy knows Belinda to be quite the comedian and is confident that Belinda was joking about the Hippopotamus dress. Several months go by and Cindy continues to refrain from wearing red dresses. One day, Cindy asks Belinda when she is going to pay her the $7,500 that she owes. Belinda laughs and says they never had a contract; therefore, she owes her nothing. Cindy wants to sue Belinda for breach of contract. Select the most appropriate answer: A. Under common law, Cindy did not give valid consideration; therefore, no contract exists. B. Under common law, Cindy was required to wear the I love Hippopotamus dress to accept Belindas offer. C. Under common law, Cindy is entitled to the $7,500 under the Doctrine of Detrimental Reliance. D. Under the UCC, Belinda is a merchant and Cindys reliance on custom and trade practice preempts.
