Question 1: Develop a solution for the following project problem.

Act	Pred.	Normal Time (Weeks)	Crash Time	Normal Cost	Crash Cost (total)	Crash cost per (week)
A	-	6	5	$900	$1000	100
B	-	8	6	$300	$400	50
C	-	4	3	$500	$600	100
D	A	5	3	$900	$1200	150
E	C	8	5	$1000	$1600	200

1. Draw the project network with Normal time.

1. What is the project duration (in weeks)? And total normal cost?

1. Compute crash cost per week for each activity.

1. Reduce the project cycle time by four weeks (Crash the network by four weeks).

1. Find the new total cost of completing the project (after crashing).
