Assuming a linear relationship between time and cost for each activity, calculate the Cost per Day saved for activity C. (Please give your answers without units and in dollars) Answer: $2500 1.2. Assuming a linear relationship between time and cost for each activity, calculate the Cost per Day saved for activity F. (Please give your answers without units and in dollars) Answer: $500 1.3. Which activity do you extend in the Crashed network to decrease the cost but remain within the minimum completion time? O a. Activity D because it has the highest cost to expedite so the duration would be extended to 4. O b. Either activity D or E because they have the same cost to expedite. O c. Activity E because it is the critical activity with the highest cost to expedite so the duration would be extended to 5. 1.4. Assume that you have 17 days to complete the project.
