Given the data and information that follow, compute the total direct cost for each project duration. If the indirect costs for each project duration's are, LE 90 (15 days), LE 70 (14 days), LE 50 (13 days), LE 40 (12 days), and LE 30 (11 days), compute the total project cost for each duration. What is the optimum cost-time schedule for the project? What is this cost?
