Use the information contained below to compress one time unit per move using the least cost method. Assume the total cost for the project is $700 and there is a savings of $50 per time unit reduced. a. Calculate and plot total direct, indirect ad project costs for each duration on a time-cost graph. b. Plot the total direct, indirect, and project costs for each of these durations on a cost-time graph. C. What is the optimum cost-time schedule for the project? What is this cost?
