The Winnipeg Police Department has five detective squads available for assignment to five open crime cases. The chief of detectives, Paul Kuzdrall, wishes to assign the squads so that the total time to conclude the cases is minimized. The average number of days, based on past performance, for each squad to complete each case is as follows:

Case Squad A B C D E 14 7 3 7 27 2 20 7 12 6 30 3 10 3 4 5 21 4 8 12 7 12 | 21 5 13 25 24 26 8
