Aaron Zeitel is a high school senior deciding which college to attend in the fall. He has narrowed his choices to three liberal arts schools: Arrington, Barton, and Claiborne. His criteria for selection are the school’s academic reputation, location (and especially proximity to his home), the cost of tuition and room and board, and the social and cultural opportunities available. Following are Aaron’s pairwise comparisons of the schools for each of the four criteria and his pairwise comparisons for the criteria:

Academic College A B C A 1 1/2 3 B 2 1 4 C 1/3 1/4 1 Location College A B C A 1 1 3 B 1 1 5 C 1/3 1/5 1 Cost College A B C A 1 1/2 1/4 B 2 1 1/2 C 4 2 1 Social College A B C A 1 3 6 B 1/3 1 3 C 1/6 1/3 1 Criterion Academic Location Cost Social Academic 1 4 1/2 3 Location 1/4 1 1/5 1/2 Cost 2 5 1 3 Social 1/3 2 1/3 1 Using AHP, determine which college Aaron should select and check the consistency of the pairwise comparison matrix for the criteria.
