Assuming that SSBA is able to start work at 11 a.m., the beginning of their arena reservation, what should the events director tell the video crew about streaming? 4. The events director is worried that the School of Engineering will not start work on its ceremony early enough to finish by 5 p.m. Assuming that everything else goes as Chapter 7 planned, by how much can the School of Engineering delay the start of SSBA's work, without then causing SSBA's ceremony to run past 5 p.m. and cause delays for the School of Arts and Sciences?CASE SCENARIO: SCHULTZ SCHOOL GRADUATION CEREMONY The Schulz School of Business Administration (SSBA) is planning its annual commencement ceremony, to be held in the university's indoor arena.
