Problem 3 Consider the following assignment problem with the goal of minimizing total cost: Job Person B 1 2 3 4 A 12 18 16 15 16 13 12 9 14 10 12 D 12 16 14 13 The cost (in $) for assigning person i (where i = 1, 2, 3, 4) to job; (where j = A, B, C, D) is given in the table. Use the Hungarian method to find the optimal assignment for the problem. What is the optimal total cost
