\begin{tabular}{|c|c|c|c|c|c|}
\hline
Activity & Normal Time (weeks) & Crash Time (weeks) & Normal Cost & Total Cost with Crashing & Immediate Predecessor(s) \\
\hline
A & 3 & 2 & $1,400 & $2,000 & --- \\
B & 2 & 1 & $2,100 & $2,850 & --- \\
C & 1 & 1 & $400 & $400 & --- \\
D & 7 & 3 & $1,500 & $1,800 & A \\
E & 6 & 3 & $950 & $1,175 & B \\

a) Based on the given information regarding the activities for the project, the project completion date = 14 weeks.
b) To reduce the duration of the project to 10 weeks at the least cost, the following is the order of what needs to be followed while crashing the activities
The first activity to crash is D by 2 weeks at a per week crashing cost of 75 dollars
Next, one should crash activity D and activity by 2 weeks for an additional total per week crashing cost of dollars
