solve e and f please

Time and cost information for a project has been provided below, along with a network diagram and a list of project paths and their respective durations. Use this information to answer the following questions: a) What is the total cost of the project, without crashing any activities (total direct plus indirect costs)? 122500 b) What is the crashing cost per day for activity D? 1250 c) According to the methodology that we used for finding a minimum cost schedule, which activity should be crashed first enter a single letter? d) If no activities other than E were crashed, and was crashed by one day, by how much would total project costs be reduced (e. what would be the savings that result from crashing E by one day)? 2000 e) If no activities other than E were crashed, and was crashed by three days, by how many days would the duration of the project be reduced (0.1.2 or 3 days, enter a single number only)? Finally, assume that nothing has been crashed yet (from the previous two questions), and crash the project to find the minimum cost schedule. The project duration will be reduced by a total of days, and the total project cost will be reduced by fi.e., total savings will be...) per Day Max Crash (days) 1 Indirect project costs = $3,000 per day (No Late Completion Penalties exist for this project) Immed Normal Normal Crash Time Crash Cost Crash Cost Acitvity Pred(s) Time (days) Cost (5) (days) (5) A 6 1,000 5 $ 1,600 $ 600 B A 5 $ 12,000 Can't be crashed C.
