The Grand Performance Hall is in the process of remodeling and is scheduled to open for business after being closed for 50 years. As part of the remodeling, it is installing a new sound system. The sound system is to be installed by Sound Systems, Inc. on or before April 10. Opening night of the hall is May 1. The contract states that "time is of the essence" because of the opening-night deadline. Sound Systems has some financial difficulties and doesn't deliver the system until April 20. Grand Hall refuses to accept it, and Sound Systems sues. What will be the result? Explain.
