Consider the following project network:

	Normal		Crash
Activity	Time(normal)	Cost(normal)	Time(crash)	Cost(crash)	Cost Slope
A	4	50	4	50	--
B	9	60	5	120	15
C	6	70	3	100	10
D	9	40	6	100	20
E	4	100	2	150	25
F	5	90	4	120	30
G	3	80	3	80	--
H	7	100	5	150	25
Total		590		870

Critical Path

1. What is the total duration (days) of the project?
2. What is the cost of crashing activity E by 1 day?
3. How does crashing activity D by 2 days affect the overall duration of the project?
4. If we want to reduce the overall duration of the project by 2 days, what is the least costly way to do it? How much will it affect the overall cost of the project?
