A Project Has the Following Activities,durations,costs,and Precedence Relationships Develop a Cost-Time Trade-Off Analysis

A project has the following activities,durations,costs,and precedence relationships:
$$\begin{array} { c c c c c c } \hline \text { Activity } & \begin{array} { c } \text { Present } \\\text { Duration } \\\text { (Weeks) }\end{array} & \begin{array} { c } \text { Accelerated } \\\text { Duration } \\\text { (Weeks) }\end{array} & \begin{array} { c } \text { Immediate } \\\text { Predecessor } \\\text { Activities }\end{array} & \begin{array} { c } \text { Present } \\\text { Cost }\end{array} & \begin{array} { c } \text { Accelerated } \\\text { Cost }\end{array} \\\hline \text { A } & 10 & 9 & - & \$ 11,000 & \$ 15,000 \\\text { B } & 15 & 13 & - & 20,000 & 25,000 \\\text { C } & 10 & 6 & \text { A } & 9,000 & 20,000 \\\text { D } & 20 & 18 & \text { A } & 25,000 & 30,000 \\\text { E } & 15 & 10 & \text { C } & 20,000 & 35,000 \\\text { F } & 17 & 15 & \text { B } & 20,000 & 30,000 \\\text { G } & 12 & 10 & \text { B } & 15,000 & 25,000 \\\text { H } & 9 & 8 & \text { D,F } & 12,000 & 18,000 \\\text { I } & 7 & 6 & \text { G,H } & 10,000 & 15,000 \\\hline \hline\end{array}$$ Develop a cost-time trade-off analysis.Detail the steps that you would use to accelerate or crash the project to its minimum duration at the lowest cost.Determine each step's cost and the duration of the project.
