Pfizer is releasing a new vaccine for pregnant people to protect their newborns from a new virus. The company has identified five tasks that must be completed and the normal time, crash time, normal cost, and crash cost for each activity. Pfizer has worked with the CDC to identify an acute need for this vaccine and would like to get the product to market 2 weeks faster to help maximize protection for the population. Activity Predecessors Normal Cost Crash Cost Normal Time (weeks) Crash Time (weeks) A - $85,000 $139,000 8 7 B A $60,000 $74,000 8 6 C A $51,000 $58,000 7 5 D A $41,000 $45,000 5 2 E B, C, D $20,000 $92,000 5 4 Calculate the initial length of the project using the normal times. By how much should each activity be crashed to reduce the length of the project by 2 weeks at minimum cost? Compute the total incremental cost of crashing the project by 2 weeks. Enter the total cost of crashing the project in dollars rounded to the nearest dollar. Treat the normal costs as sunk costs and only enter the additional marginal cost associated with crashing
