Hello students, here in the given problem given the design time reduction that is 4 days and the activities on the critical path are a to c, c to a.
00:09
Therefore, the first one to find the activity for a that is normal time is equal to 6 days and the crash time is equal to 5 days.
00:30
Therefore, the normal cost is $900.
00:38
Therefore, the total cost crashing is equal to $1000.
00:50
So, the crashing time is equal to normal time minus crash time.
01:09
Therefore, the normal time is 6 and crash time is 5.
01:12
Therefore, it is 1 day.
01:15
Therefore, the crashing cost is equal to total cost with crashing minus normal cost.
01:37
Therefore, the cost value is $1000 minus $900.
01:45
Therefore, this value is $100.
01:50
And to find for activity c, the normal time is equal to 4 days and the crash time is equal to 3 days.
02:14
Therefore, the normal cost is equal to $500 and total cost with crashing is equal to $800...
