Scenario 1: On January 1, 2023, Matt went to AJM Lumber Company to shop for oak flooring planks. That day, AJM Lumber Company gave Matt a written and signed offer to sell the required planks for $5,000. The offer included the following statement: "AJM Lumber Company promises that this offer will remain open until February 15th, 2023." On February 1, the price of wholesale lumber tripled and AJM Lumber Company sent Matt a letter saying that it was immediately revoking its January 1st offer.

Scenario 2: On January 2, 2023, Matt told his neighbor Tom that he would be interested in buying Tom's car. Tom had never sold a car before, and that day, Tom gave Matt a written and signed offer to sell his car to Matt for $8,000. The offer included the following statement: "I promise that this offer will remain open until February 16th, 2023." On February 2, Tom's brother offered to buy the car for $9,000 and Tom sent Matt a letter saying that he was immediately revoking his January 2nd offer.

Scenario 3: On January 3, 2023, Matt asked TreeHouse Snow Removal Company how much it would charge to plow Matt's Driveway while Matt was out of town in the month of March. That day, TreeHouse Snow Removal Company gave Matt a written and signed offer to plow his driveway each week in March for $300. The offer included the following statement: "TreeHouse Snow Removal Company promises that this offer will remain open until February 17th, 2023." On February 3, the price of gasoline tripled and TreeHouse Snow Removal Company sent Matt a letter saying that it was immediately revoking its January 3rd offer.

For each of the three scenarios, write 2-3 sentences explaining why each offer can or cannot be revoked. Make sure you identify and discuss the applicable law.
