Q2 (W3). The following activity table is for a project that may need to finish earlier. The table provides you a normal activity time and its normal activity cost. It also provides you a shortest finish time and a higher cost for crashing that activity. On its normal activity time, the shortest critical path has a finish time of 27 days (See the figure). What is the best way to crash the project such that it can be finished in 23 days? How much is the "extra crashing cost" on top of the normal activity cost for this crashing plan? Please provide the sequence of your crashing plan.
