Above is the original breakdown if seaburg were to consider doing all tasks. Seaburg construction company is considering subcontracting an outside construction firm to assist in completing the project. This construction firm will supply a second crane and work hand in hand with the Seaburg construction staff. The overall effect will be that the project may be completed sooner than expected as a result of supplying additional resources. Seaburg management team has outlined the cost and time savings benefit for the tasks that can be accelerated as a result of hiring the outside firm as follows:

NORMAL CRASH ADDITIONAL ACTIVITY TIME TIME COST to ACCELERATE B 16 hrs 8 hrs $15,000 C 72 hrs 48 hrs $ 50,000 E 24 hrs 16 hrs $ 10,000 F 36 hrs 24 hrs $ 15,000 K 16 hrs 8 hrs $ 15,000 M 24 hrs 16 hrs $ 35,000

Should Seaburg hire this firm? If so, what activities should be crashed and by what amounts? Assume Seaburg can hire the firm for only the appropriate tasks needed.
