Below is a training project with normal times and crash times (in parentheses), find the cost-duration history. Assume indirect costs for facilities and equipment are $100 per day. The data are:

Please indicate how many days each activity is crashed, and why we are crashing the activity for that many days. (Ex: If we are crashing activity 3-4 for 3 days, state WHY 3 days of crashing is being done)

\begin{tabular}{ll} Activity & \multicolumn{1}{l}{ Time Reduction, } \\ \hline 1-2: Obtain room & $30 first, $50 second \\ 2-3: Select trainer & $80 \\ 34 : Invite personnel & $25 first, $60 second \\ 2-4: Check budget & $30 first, $70 second, $90 third \\ & 6(4) \end{tabular}
