Hilda Homeowner said to her neighbor, Paulette Painter, If you paint my house, Ill pay you $1,500. All you must do is finish by the end of the next month. My price assumes that you will pay for all of the paint and any needed supplies. Paulette decided to paint the house. She purchased some supplies, as well as enough custom-colored paint to complete the job. On the morning that Paulette was about to begin painting, Hilda told her that she had changed her mind and would not pay Paulette to paint the house. Discuss the rights of the parties in this situation.
