A project consists of the following activities, normal durations (days), immediate predecessors, cost per day to crash ($000/day), and available days to crash.

Activity	Normal Duration(days)	Immediate Predecessor(s)	Cost per Day to Crash ($000/day)	Available Days to Crash
A	8		9	5
B	8		2	4
C	6		4	3
D	9	A	6	7
E	20	A	3	7
F	11	B, D	1	5
G	9	B, D	7	5
H	12	C, G	8	7

a. This part of the question is not part of your Connect assignment.

b. Calculate the project duration using normal activity durations.

Project duration days

c. Determine the minimum-cost crashing plan that will take 16 days off the project duration.

The critical path after crashing is (Click to select) A-E, A-D-G-H, and B-G-H A-E, A-D-G-H and A-D-F .

Expected duration of the project after crashing is days.
