Question

How are marketing and sales will affect the commercial world?

Answer 1

Marketing vs. Sales. Marketing and sales are both aimed at increasing revenue. They are so closely intertwined that people often don't realize the difference between the two. Indeed, in small organizations, the same people typically perform both sales and marketing tasks.

but they can affect the commercial by over pricing in places of population and  more wealthy places to get more revenue, and sales could get more low because of the prices or they can raise depending on where it is.
