Problem $17-14($Static$)$

The project manager of a task force planning the construction of a domed stadium had hoped to be able to complete construction prior to the start of the next college football season. After reviewing construction time estimates, it now appears that a certain amount of crashing will be needed to ensure project completion before the season opener. Given the following time and cost estimates, determine a minimum$-$cost crashing schedule that will shave five weeks off the project length. Note: No activity can be crashed more than two weeks.
