b. Which two activities cannot be expedited because their expediting cost exceeds the weekly limit?
c. Which two activities are unlikely candidates for expediting because they are not on the critical path?
d. Set up a table and show step-by-step which activities should be expedited to shorten the project time. What is the minimum time the project will take if Cherry expedites the project as much as she can and stays within her limits?
e. Why is Cherry’s limit exceeded if you try to shorten the project by one day more?
