Based on Franklin and Koenigsberg (1973). The city of Busville contains three school districts. The numbers of minority and nonminority students in each district are given in the file P04_121.xlsx. The local court has decided that each of the town’s two high schools (Cooley High and Walt Whitman High) must have approximately the same percentage of minority students (within 5%) as the entire town. The distances (in miles) between the school districts and the high schools are also given in the same file. Each high school must have an enrollment of 300 to 500 students. Determine an assignment of students to schools that minimizes the total distance students must travel to school.
