To reduce the project length by three days, we need to find the activities on the critical path that have the lowest crash cost per day. From the table, we can see that activities A and D are on the critical path and have the lowest crash cost per day ($200/day for both). We can crash activity A by 2 days and activity D by 1 day for a total cost of $2,500 ($1,800 for activity A and $700 for activity D). This is the cheapest way to reduce the project length by three days.
