Table J.13
Professor Gable and his graduate assistant are grading student term papers.The graduate assistant must first make a general evaluation and then Professor Gable makes the final grade evaluation.There are four term papers to evaluate: W,X,Y,and Z.Because the length and content differ,each paper will differ in evaluation time.The times,in hours,are estimated to be:
-Use the information in Table J.13.How much time will it take to grade all four papers? That is,what is the makespan for this project?
A)fewer than or equal to 22 hours
B)greater than 22 but fewer than or equal to 23 hours
C)greater than 23 but fewer than or equal to 24 hours
D)greater than 24 hours

The makespan is the longest time required to complete all four papers. Paper 1 takes 6 hours, Paper 2 takes 7 hours, Paper 3 takes 5 hours, and Paper 4 takes 4 hours. The longest time is 7 hours, so the makespan is greater than 22 but fewer than or equal to 23 hours.
