Problem #2 Suppose you are considering crashing a project. The projects network diagram (AON format) is shown on the Problem-2 Data Worksheet, along with the table identifying the critical activities and the crash cost for all tasks.

2.1 What is the projects critical path, and what is its length? (10 points)

2.2 What is the normal cost of the project? (10 points)

2.3 Crash the project (shorten the project duration) by 3 days. List the activities for the first, second, and third crashes and the total crash (additional) cost. (20 points)
