Answer:
Benefit: 10,000
Explanation:
Salaries terminated: 390,000
decrease in misc overhead 30,000
outsourcing tariff: (410,000)
Benefit: 10,000
The most questions most important issue is how to account the 120,000 assistant and the fixed cost that will be allocate to other department.
The truth is, this are not relevant cost.
As the company would hire this assistant in the near future if the H/R is not outsource as the company won't keep them if they aren't useful.
Also the allocate cost are cost from other operations not related to human resources. So ust be disregard from the calcualtion.
We should consider only the explicit decrease, which are the salaries and fewer tracable overhead.
