1) Trevor wants to buy a new home. He is interested in the house located across the street, owned by Jack and Connie. Trevor has a professional real-estate appraiser appraise Jack and Connie's home, and the appraiser appraises the house at $300,000. Trevor asks Jack and Connie if they would sell their house to him for $275,000. Jack and Connie agree, and the three memorialize their agreement in a written purchase agreement signed by all of them. The closing is scheduled for June 30. On June 25, Jack and Connie tell Trevor that they will not sell the house to him. Is Trevor entitled to specific performance of the agreement, or must he accept damages for breach of the contract? Fully explain your answer, including any rule or rules that support it. 2) Hardhart, Inc. sells 200 yellow construction-safety hats to BuilderSolutions, a retailer that provides tools, workwear, and other equipment to the construction industry. BuilderSolutions's purchasing manager calls Hardhat's telephone order line, places its order, pays the contract price with a credit card, and receives the 200 construction hats as requested. However, the hats are made of ordinary, thin plastic and do not provide any safety benefits to the wearer. In fact, when BuilderSolutions inspects the shipment of hats, one hat is dropped on the floor and the hat cracks. When BuilderSolutions calls to complain, Hardhat claims that the hats were not sold with any kind of a warranty, and it refuses to refund BuilderSolutions's contract price. Is Hardhat right? Fully explain your answer, including any rule or rules that support it. 3)Tasha operates a business consulting firm. She contracts with Raleigh to provide business consulting services for his new company for a period of six weeks. Tasha and Raleigh sign a written agreement. Assume that it is a completely integrated agreement. After signing the agreement and working on Raleigh's project for three days, Tasha asks Raleigh if he would be willing to extend the time for her to work on the project to seven weeks to give Tasha some additional time to accumulate data for the project. Raleigh verbally agrees that it would be good to have more data and agrees to extend the time for performance to seven weeks. At the end of the six-week period, Tasha has not completed her work, and Raleigh refuses to pay. If Raleigh argues that the verbal agreement is inadmissible evidence under the parol evidence rule, will his argument be successful? Fully explain your answer, including any rule or rules that support it
