Before buying a house, dean and donna testa hired ground systems, inc. (gsi), to inspect and describe the sewage and water disposal system. gsi reported that a split sewage and water disposal system was in place with a watertight septic tank, a wastewater tank, a distribution box, and a leach field. the testas bought the house. later, dean testa noticed that the system was not as gsi described; there was no distribution box or leach field. furthermore, there was only one tank, and the tank was not watertight. the testas arranged for the installation of a new system and sold the house. assuming that gsi is liable for a breach of contract, what is the measure of damages?
