Crashing - Deciding what to tackle first Given the data and information that follows in this example, compute the slope and maximum reduction time for each activity. Also compute the total direct costs for durations 32, 31, 30, 29, 28, and 27 time-units. Assume indirect costs of $170, $150, $129, $122, $118, and $110, respectively, for each listed duration. What are the optimum project duration and cost?
