PM Problem (Exercise 4). Determine the project's cost and duration alternatives. Times (durations) in days, costs are in $K. Perform three cycles of the process: determine the crash design, the normal design, and the next two designs (a total of 4 project designs). Code NT CT NC Prec.

Crash design duration: 2. Normal design duration: 3. Normal design critical path: (type only the number) (type only the number) (do not place separators between the letters, for example if the critical path is X-Y-Z write XYZ) 4. What activity will be crashed in this iteration: 5. Project cost after first crash: dollar sign, or K letter) 6. Project cost after second crash: commas, dollar sign, or K letter) (a letter) (type only the number with no commas. (type only the number with no
