question 58

Multiple Choice

You have collected the data for a Time-Cost CPM Scheduling model analysis. The time is in days and the project "direct costs" are given below. The indirect costs for the project are determined on a daily duration basis. If the project lasts 16 days the total indirect costs are $400, 15 days they will be $250, 14 days they will be $200, and 13 days they will be $100. At what day do we achieve the lowest total project cost (i.e., direct plus indirect costs) ?

• A) 16 days
• B) 15 days
• C) 14 days
• D) 13 days
• E) 12 days
