A school district in Sarnia is considering where to locate its central office. Note: the office must be located at an existing school for cost reasons. There are five schools in the district, with locations and size given in the following table. Location Size (Enrollment) (x,y) Coordinates x-calcs y-calcs A 2,500 (5,5) B 1,000 (0,5) C 10,000 (0,0) D 4,500 (5,0) E 7,500 (2,1) Required: 1. Use the Centre-of-Gravity method to determine at which school the central office should be located to minimize the average distance between the office and students. [5 marks] 2. Consider one intangible (non-financial) cost that should be considered when making this location decision. [1 mark] NOTE: X-calc and y-calc values must be shown to receive marks.
