Id say its A, because entrepreneurs start a business to make a profit.
Interpersonal communication
It might be easier because most credit unions require some kind of affiliation while banks will let anyone with money open and account.
Answer:
Marginal cost will equal average total cost when marginal cost is at its lowest point.
Explanation:
The marginal cost curve always intersects the average total cost curve at its lowest point because the marginal cost of making the next unit of output will always affect the average total cost. As a result, so long as marginal cost is less than average total cost, average total cost will fall.
When marginal cost is below average total cost, average total cost will be falling, and when marginal cost is above average total cost, average total cost will be rising. A further m is most productively efficient at the lowest average total cost, which is also where average total cost (ATC) = marginal cost (MC).
Because if you chose the one with the higher opportunity cost you are wasting resources while you could be doing something more effective instead.
