1. Given the following network diagram, and the table with the normal time (NT), crash time (CT), normal cost (NC), and crash cost (CC). Which activity or activities would you crash so that the original project time will be reduced by a third week in the most economical (i.e., cheapest) way possible?

2. This is a continuation of the previous question: What would be the total cost to complete this project from beginning to end if the project is completed three weeks earlier than the normal time?
