The coach of an age group swim team needs to assign swimmers to a 200-yard medley relay team to send to the Junior Olympics. Since most of his best swimmers are very fast in more than one stroke, it is no clear which swimmer should be assigned to each of the four strokes. The five fastest swimmers and the bes times (in seconds) they have achieved in each of the strokes (for 50 yards) are Stroke Backstroke Breaststroke Butterfly Freestyle Carl 37.7 43.4 33.3 29.2 Chris 32.9 33.1 28.5 26.4 David 33.8 42.2 38.9 29.6 Tony 37.0 34.7 30.4 28.5 Ken 35.4 41.8 33.6 31.1 The coach wishes to determine how to assign four swimmers to the four different strokes to minimize the sum of the corresponding best times.
