Only having trouble with the circled part

Problem 16-6 The following table contains information concerning four jobs that are awaiting processing at a work center. Job Time (Days) 14 10 7 Due Date (Days) 20 16 15 17 a. Sequence the jobs using (1) First come, first served, (2) Shortest processing time, (3) Earliest due date, and (4) Critical ratio. Assume the list is by order of arrival Sequence for First come, first served Sequence for Shortest processing time Sequence for Earliest due date Sequence for Critical ratio A-B-C-D D-C-B-A C-B-D-A A-C-D-B b. For ech of the methods in part a, determine (1) the average job flow time, (2) the average tardiness, and (3) the average number of jobs at the work center. (Round your intermediate calculations and final answers to 2 decimal places.) First Come, First Served Shortest Processing Time Earliest Due DateCritical Ratio 26 19.7 21 Average job flow time Average tardiness Average number of jobs 2.8 2.14 2.2
