1. Given the following data, compute the slope and maximum number of times an activity can be crashed. Use the table provided. Also compute the total direct costs for durations 32, 31, 30, 29, 28, and 27 time-units. Assume indirect costs of $170 for 32, $150 for 31, $129 for 30, $122 for 29, $118 for 28, and $110 for 27 time-units, respectively. What are the optimum project duration and cost?
