The earliest due date (EDD) rule schedules jobs in ascending order of their due dates. Following this rule, the jobs are sequenced as E, A, D, B, C. Calculating the completion time and tardiness (if any) for each job: - Job E finishes on day 10 (due day 18), so no tardiness.- Job A finishes on day 26 (due day 24), so 2 days late.- Job D finishes on day 34 (due day 28), so 6 days late.- Job B finishes on day 57 (due day 30), so 27 days late.- Job C finishes on day 79 (due day 40), so 39 days late.The average tardiness = (0 + 2 + 6 + 27 + 39) / 5 = 74 / 5 = 14.8 days, which is more than 10 but less than or equal to 20 days.
