I need help answering it

2. A homeowner met with a contractor regarding remodeling the homeowner's kitchen. At the conclusion of their meeting, the contractor told the homeowner that he would charge her between $9,000-$10,0000 for the work, but that he would get back to her with a definite price when he returned to his office. When he arrived at his office, the contractor had a voicemail from the homeowner, saying that she would pay hm $9000 for the work they discussed. The contractor promptly returned her phone call and left her a voicemail saying that he would do the work for $9500, which the homeowner received. The next day, the contractor, having a change of heart, tried unsuccessfully to reach the homeowner by phone. He left her a voicemail that would do the work for $9000 after all and that he would start the following day unless he heard otherwise from her. The next day, the contractor showed up at homeowner's house ready to begin. What best describes the relationship between the parties
