Tony Shear, president of Georgia Carpet Installation, Inc., began negotiations with David and Juanita Thompson for the sale and installation of carpeting, carpet padding, tile, and vinyl floor covering in their home. Shear drew up a written proposal that referred to Georgia Carpet as "the seller" and to the Thompsons as the "customer." The proposal listed the quantity, unit cost, and total price of each item to be installed. The total price of the job was $4,777.75. Although labor was expressly included in this figure, Shear estimated the total labor cost at $926. Mrs. Thompson in writing accepted Shear's written proposal soon after he submitted it to her. After Georgia Carpet delivered the tile to the Thompson home, however, Mrs. Thompson had a disagreement with Georgia Carpet's tile man and arranged for another contractor to perform the job. Georgia Carpet brought an action against the Thompsons for breach of contract.

Does the UCC apply to this contract? How do you know?
