Marketing Cost Analysis Starts with the Assumption That

Marketing cost analysis starts with the assumption that:

A) "natural accounts" are more useful than "functional accounts."
B) marketing expenditures are made for a specific purpose--and so it makes sense to allocate costs to different market segments, customers, or products.
C) all marketing expenditures should be treated as overhead expenses.
D) overall profit is what counts--so it isn't critical if some market segments, products, or customers are unprofitable.
E) All of the above.
