45. The Villa Arriba town has three schools. The town's school board of directors
has decided to redistribute the school areas assigned to each school. The town is
divided into 10 sectors, each of them with an estimated population of students
for the next years. The distance (in km) from the centre of each sector to each
school has been determined. The following table reports these data, as well as
the maximum capacity of each school:

The board of directors wants to determine how many students of each sector
must attend each school in order to minimize the total travelled distance by the
town's students as a whole.
