The following table contains a list of activities, with precedence requirements and crash costs. All start and finish times and crash costs are on a per -week basis.

1. Determine the project cost and duration without crashing.

2. Determine the least expensive project cost if the duration is to be 10% shorter than normal project duration.

3. Determine the least expensive project cost if the duration is to be 20% shorter than normal project duration.

4. Create a graph that shows project expediting cost plotted as a function of the reduction in project

duration.

B	12	8	1500	2000	A
C	16	12	2200	3000	A
D	8	7	2500	3000	B
