Paths:
i) A -> C -> F -> G
ii) A -> B -> E -> G
iii) A -> B -> D -> E -> G
i) Determine project expected completion date?
ii) Determine total cost needed for completing the project on normal time?
iii) If you want to decrease time needed to complete the project to only 29 weeks, which activity must be crashed, and how much will the increase total cost? Illustrate Cost Changes and Activities Changed in workings to get answer.
