10. For the following problem, manually construct a project network, activity float chart, and crashing table. List and box the answers to the following questions: (20 points) a. What is the critical path time? b. What is the critical path? c. What is the normal cost to complete the project? d. What is the cost to crash the network by 4 weeks? (Show the crashing cost schedule.) e. What is the cost of crashing to the max? (Determine this manually, then use QM to check the answer.)
