The following is a table of activities associated with a project at Rafay Ishfaq's software firm in Chicago, their durations, what activities each must precede and the crash cost to reduce duration per week: Activity Duration $($weeks$)$ Precedes Crash Cost$/$Week A $($start$)$ B$,$ C B E C F E F F $($end$)$ Part $2$ Suppose that Rafay is only given weeks $($instead of $)$ to complete the project. By how many weeks should each activity be crashed in order to meet the deadline? Assume that you can crash an activity down to $0$ weeks duration. Activity Each Activity Should be Reduced BY $($weeks$)$ A enter your response here week$($s$)$ Suppose that Rafay is only given $8$ weeks $($instead of $10)$ to complete the project. By how many weeks should each activity be crashed in order to meet the deadline? Assume that you can crash an activity down to $0$ weeks duration.
