The crash cost per time for this activity is given as $50.
The crash cost per time can also be defined to be the slope. The slope is given as rise / run.
Hence we have this formula to solve it with
(crash cost minus normal cost)/(normal time minus crash time)
When we input value we have
300-150/12-9
= 150/3
= $50
Hence the crash cost per time is solved as $50.
