    The project manager of a task force planning the construction of a domed stadium has 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 the cost estimates, determine a minimum cost crashing schedule that will shave five weeks off the project length. Note: no activity can be crashed for more than 2 weeks.
