undefined Student number is 4

1. [25 pts.] Five workers are available to perform four jobs. The time it takes each worker to perform each job is given in the following table. For X, substitute your student numbers last digit and calculate the time required to perform each job for the given table. (For example: If your student number last digit is 1, time required worker 1 to finish job 1 is 13+1=14) The goal is to assign workers to jobs so as to minimize the total time required to perform the four jobs. Use the Hungarian method to solve the problem. (Show each step and calculations clearly). Worker 1 Worker 2 Worker 3 Worker 4 Worker 5 Job 1 13+X 15+X 15+X 9+X 19+X Time(hours) Job 2 Job 3 18+X 13+X 11+X 23+X 12+X 15+X 15+X 18+X 15+X 11+X Job 4 18+X 19+X 21+X 21+X 15+X Summarize your solution below: X1_=1, X2_=1, X3_=1, X4_=1, and X5_=1, z=
