Answer the next three questions using the following information:

Five critical path activities are candidates for crashing on a CPM network. Activity details are in the table below.

Activity	Normal Time	Normal Cost	Crash Duration	Crash Cost
A	9 days	$8,000	7 days	$12,000
B	5 days	$2,000	3 days	$10,000
C	12 days	$9,000	10 days	$12,000
D	10 days	$10,000	9 days	$15,000
E	7 days	$6,000	7 days	$6,000

1. Which activity should be crashed first to cut one day from the project's duration?

2. Which activity should be the next activity crashed to cut a second day from the project's duration?

3. Assuming no other paths become critical, if the project is shortened to its maximum, how much cost will be added to the project.
