Overhead project costs (Indirect costs) are $70 per day.

Please crash the project and find the project schedule with the lowest total cost (indirect cost + direct cost).

Rule of thumb:

Crash the project one period at a time.

Crash the least expensive activity that is on the critical path.

Critical path will very likely change after each crashing, find new critical path each time before crashing.
