Choose the correct network diagram for this project. StartFinishA7B4C5D5E5F3G5 In the diagram, there are 2 rectangles. The one on the left is labeled Start, and the one on the right is labeled Finish. There are 7 circles labeled inside the circle using the letters from A to G. There is a number below the letter inside each circle. There are arrows that indicate the flows through the circles from Start to Finish as follows: Rectangle Start has an arrow that connects to circle A 7, circle A 7 connects to…

Activity Normal Time Normal Cost Crash Duration Crash Cost A 9 days $8,000 7 days $12,000 B 5 days $2,000 3 days $10,000 с 12 days $9,000 11 days $12,000 a. What is the crash cost per unit time for activity A? b. What is the crash cost per unit time for activity B? c. Which activity should be crashed first to cut one day from the project's duration; how much is added to project cost? d. Which activity should be the next activity crashed to cut a second day from the project's duration; how much is added to project cost? e. Assuming no other paths become critical, how much can this project be shortened at what total added cost?
