Baseball umpiring are currently working in four cities where three-game series are beginning. When these are finishes, the crews are needed to work games in four different cities. The distances (miles) from each of the cities where the crews are currently working to the cities where the new games will begin are shown in the following table: The X indicates that the crew in Oakland cannot be sent to Toronto. Determine which crew should be sent to each city to minimize the total distance traveled. How many miles will be traveled if these assignments are made?
