The normal and crash durations of the various activities along with the associated costs are also shown above in Table. Crash cost in the last column in the table is the total crashing cost of the related activity (For example, if the duration of the activity A is reduced from 8 days to 6 days, cost of the activity A increases from 1800 USD to 2200 USD). Assignment Draw the network, find the critical activities and consider crashing of the project time. Answer the following questions. Questions: Please write the critical activities. What is the project completion time? What is the normal cost of the project? What will be the total cost if the project time is crashed for 36 days
