A project has 7 activities (A, B, C, D, E, F, and G). A proceeds B, C, and D. E follows C. F follows D. G follows B, E and F. Their normal time and costs are (5,9,8,7,4,6,3) and ($90,100,80,60,70,50,200). Their crash time and cost are (4,5,7,6,2,4,2) and ($120,140,120, 80,190,190,289). Compute the total direct cost for each project duration. If the indirect costs for each project duration are $450 (21 time units), $400 (20), $350(19), $300(18), $250(17) and $200 (16), (A) compute the total project cost for each project duration. (B) What duration represents the lowest total project cost? (C) What is this cost?
