Please answer A & B.

Consider project time and cost data in Table 1. The indirect cost of the project is $200 per day. Table 1. Normal and crash times/costs for the project (Note: Times are in days) Task Immediate Normal Crash Normal Crash Predecessors Time (days) Time (days) Cost ($) Cost ($) 200 200 10 600 1,000 12 625 1,000 B 6 700 800 200 500 C,D 400 840 E 14 1,000 1,440 E ,F 10 8 1,100 1,460 B 10 H a) Determine the project duration and the cost for "No Crash Schedule" (CPM). b) Determine the project duration and the cost for "Maximum Crash Schedule". c) Construct a Linear Programming model to determine the optimal duration of the project and solve it using LINDO. Be sure to state precisely the definitions of your decision variables, and explain in a few words the purpose of the first three constraints. d) Using your LINDO output determine the amounts by which activities are to be "crashed" and completion times of the activities for the optimal project duration. e) Construct the project network based on the optimal solution obtained from LINDO. Determine the minimum cost of the project
