(20 points) For the above problem, you are considering the decision of whether or not to crash the project. To conduct the analysis, you have determined the "precrash" and "postcrash" activity durations and costs, shown in the table below: a. What is the cost of the project? b. Calculate the per day costs for crashing each activity. c. Which are the most attractive candidates for crashing assuming all activities in the network are critical? d. Which are the most attractive candidates for crashing assuming that the critical path is on activities CGJ and you have only $1500 budget for crashing? Explain.
