Question 4 3 pts Consider the following network: The "Start" activity is followed by activity A. Activity A is followed by Activity C. The "Start" activity is also followed by Activity B. Activities D and E are successors from Activity B. Activities C and D and E are predecessors to the "Finish" milestone. Durations are in days. What is the smallest extra cost to shorten ("crash") the total project schedule to 10 days? (If you can crash a task by two days, you may choose to crash it by just one day at half the extra cost. Hint: You may find it easier to draw the network first.) Original New "Crashed" Extra Cost to Crash Activity Duration Duration the Duration Start 2 $8,000 A 5 4 $10,000 ? ? $12,000 ($6,000 per B 6 4 day) C 4 3 $12,000 D 3 $5,000 E 2 $3,000
