Suppose management of Spartan Cabinets has developed additional information for the project described in problem 10:
To illustrate, activity A can be crashed by up to 3 weeks, at a cost of $2,000 per week. Therefore, activity A can be 8, 7, 6, or 5 weeks long, depending on how much money
Spartan Cabinets decides to spend to crash the activity.
a. What is the cheapest way to crash the project by 2 weeks?
b. What is the shortest time in which the project can be completed? (Assume that cost is not a concern.)
