e following is a table of activities associated with a project at Rafay Ishfaq's software firm in Chicago, their durations, what activities each must precede and the crash cost to reduce duration per week:

Activity	Duration (weeks)	Precedes	Crash Cost/Week
A (start)	1	B, C	$400
B	1	E	$100
C	4	F	$200
E	2	F	$300
F (end)	2		$400

Part 2: Suppose that Rafay is only given 5 weeks (instead of 7) to complete the project. By how many weeks should each activity be crashed in order to meet the deadline? Assume that you can crash an activity down to 0 weeks duration.
