Consider the Project Network and Data Shown Below ADetermine the Critical Path

Consider the project network and data shown below: $\begin{array}{|c|c|c|c|c|c|}\hline\text { Activity } & \begin{array}{c}\text { Normal Time } \\\text { (Months) }\end{array} & \begin{array}{c}\text { Crash Time } \\\text { (Months) }\end{array} & \begin{array}{c}\text { Normal } \\\text { Cost }\end{array} & \begin{array}{c}\text { Crash } \\\text { Cost }\end{array} & \begin{array}{c}\text { Crash } \\\text { Cost/Month }\end{array} \\\hline \text { A } & 3 & 2 & \$ 100,000 & \$ 150,000 & \\\hline \mathrm{B} & 6 & 4 & \$ 200,000 & \$ 320,000 \\\hline \mathrm{C} & 2 & 2 & \$ 90,000 & \$ 90,000 \\\hline \mathrm{D} & 2 & 1 & \$ 180,000 & \$ 250,000 \\\hline \mathrm{E} & 4 & 2 & \$ 225,000 & \$ 450,000 \\\hline \mathrm{F} & 7 & 6 & \$ 80,000 & \$ 120,000 \\\hline \mathrm{G} & 4 & 2 & \$ 310,000 & \$ 500,000 \\\hline \mathrm{H} & 2 & 2 & \$ 400,000 & \$ 400,000 \\\hline\end{array}$
a.Determine the critical path.
b.If management wants the project done in one less month, which activity should they crash?
