Given the data and information that follow, compute the slope and maximum reduction time for each activity and the total direct costs for durations 32,31,30,29,28, and 27 time units. Assume indirect costs of $170, $150, $129, $122, $1 18, and $110, respectively, for each listed duration. What are the optimum project duration and cost?
