Question #4: Assume the network and data that follow. Compute the total direct cost for each project duration. If the indirect costs for each project duration are $400 (19 time units), $350 (18), $300 (17), and $250 (16), compute the total project cost for each duration. Plot the total direct, indirect, and project costs for each of these durations on a cost-time graph. What is the optimum cost-time schedule for the project? What is this cost? (25 Points) 2a ACT.
