Pаige, а 15-yeаr-оld with an entrepreneurial spirit, nоtices that her neighbоr Desmond has posted signs advertising a yard sale coming up the next weekend. Paige knows that Desmond, a retiree in his seventies, has bad knees and may struggle with moving some of his heavier items for sale. Paige knocks on Desmond’s door and says that she could help him run his yard sale if she can keep a portion of the profits, suggesting 25%. Desmond, who is known to be quite frugal, tells her that he can instead pay her a minimum of $50 for the day, but that if he sells at least $1,000 in the yard sale, he’ll instead pay her $150. Paige tells Desmond “you’ve got yourself a deal!” and happily prepares for the weekend yard sale. On the day of the yard sale, Paige runs around all day, helping customers and assisting Desmond in making sales. Towards the end of the day, Desmond has sold $850 worth of goods, when Tom, another neighbor, approaches Desmond with an offer to buy an ornate lamp for $300. Desmond, hoping to avoid having to pay Paige extra, tells Tom to come back tomorrow and he can buy the lamp for only $250. Tom agrees and walks away. Desmond tells Paige that the yard sale is over, and that as they only made $850 that day, he will pay her the $50 they agreed on. Paige is quite upset, as she overhead Desmond’s conversation with Tom. Paige asks you whether she has any right to seek more than the $50 Desmond paid her. Discuss.
