Consider the following project network and cost/time information. This project has a $80/day indirect cost:

Activity	Precedence	Normal Time	Crash Time	Normal Cost	Crash Cost
A	-	5	4	50	70
B	A	4	2	70	80
C	A	5	2	50	140
D	B	1	Can't be crashed	90	-
E	C	2	1	50	60
F	D, E	3	1	200	600

• What is the direct cost of completing this project using the normal times? (Enter a numerical value without "$" or ",")
• What is the total cost of completing this project using the normal times? (Enter a numerical value without "$" or ",")
• If you were asked to reduce the project completion time by one time unit, which activity would you crash?
• What is the indirect cost of this project if we reduce its completion time by two days? (Enter a a numerical value without "$" or ",")
• What is the total cost of this project if we reduce its completion time by two days? (Enter a a numerical value without "$" or ",")
