Only answer if you're absolutely certain and show your work, please.

The following CPM network has estimates of the normal time in weeks listed for the activities: (Diagram: explained below: v)

*A(4) to B(5) to *D(6) to F(5) to *G(5)

^A(4) also goes to C(7) to ^D(6) to E(8) to ^G(5)

a. Identify the critical path.

	A-C-D-E-G
	A-B-D-E-G
	A-B-D-F-G
	A-C-D-F-G

b. What is the length of time to complete the project?

Number of weeks

c. Which activities have slack, and how much?

	B, 2 week(s); F, 3 week(s).
	B, 5 week(s); E, 4 week(s).
	C, 2 week(s); F, 5 week(s).
	C, 2 week(s); E, 4 week(s).

Here is a table of normal and crash times and costs.

ACTIVITY	NORMAL TIME	CRASH TIME	NORMAL COST			CRASH COST
A	4	3	$	7,400		$	9,000
B	5	3		5,300			8,800
C	7	6		7,500			10,500
D	6	5		2,700			4,800
E	8	7		2,700			3,700
F	5	4		5,500			7,200
G	5	4		4,600			7,800

d-1. Which activities would you shorten to cut two weeks from the schedule in a rational fashion?

	E A
	C E
	D F
	B D

d-2. What would be the total incremental cost?

Total incremental cost $

d-3. Is the critical path changed?

	No
	Yes
