For the Solved Problem at the end of this chapter, assume that the most likely times (m) are the normal activity times and the optimistic times (a) are the activity crash times. Further assume that the activities have the following normal and crash costs:

Activity Costs (Normal Cost, Crash Cost)

1 ........($100, 400)

2 .....($250, 400)

3 ......($400, 800)

4 .....($200, 400)

5 .....($150, 300)

6 ......($100, 100)

7 .......($300, 500)

Crash the network the maximum amount possible and indicate the total crash cost.
