Provide a graph of Prob. 20 textbook solution results by plotting a curve or a series of cycles of crash in steps, plotting TOTAL COST vs. DURATION. Elements of your graph at least should include: ND, NC, CD, CC, LCD, and LC along the curve. 20. Calculate the normal, least-cost, and crash durations for the following project. Calculate the cost associated with each duration. Indirect (overhead) costs are 100ドル per day.
