ANSWER--17
It costs $75 per day for each day that a construction crew is on site.
The project manager determines that most activities can be crashed
and has listed the crashing costs next to the minimum time for each
activity. Use this information to determine the lowest cost for this
project. All times given are in days.ActivityNormal TimeMinimum
