Central New York Bank has three regional offices located in Utica, Syracuse, and Albany. The Bank is planning on how to assign the three recently hired junior managers, Bob, Cindy, and David, to its three regional offices for job training. The banks executive office wants no more than one junior manager for each regional office.

The banks human resources office estimates the assignment costs as follows:

Junior Manager/Location	Utica	Syracuse	Albany
Bob	$1150	$1400	$1325
Cindy	$1285	$1395	$1200
David	$1215	$1280	$1170

Part a Use the network concept and create a network program for the above problem to find its minimized cost. Make sure you define the variables used and clearly list the objective function and constraints. You do not need to solve the program.

Part b Later the human resources office receives an update that David has left Central New York Bank and now works for a different bank. How will you modify your above program to reflect this update?
