please explain how and show all work

10. A project has these activities, precedence relationships, and activity durations: Immediate Predecessor Activities Activity Duration (days) Immediate Predecessor Activities Activity Duration (days) Activity Activity d 16 o I c.b oooo . h . e,f,g 22. From Problem 10: a. If you have not already done so, construct a CPM network for the project, compute EF, LF, and the slack for each activity, and write their values on the CPM network. What is the critical path and its duration? b. Given the costs of crashing the activities of the project below, develop a cost-time trade-off analysis. Detail the steps that you would use to accelerate or crash the project so that it could be completed in no more than 41 days. What are the new cost and duration of the project?
