I feel stressed reading this question as it has no context but the question is asking for your opinion. there really is no wrong answer
The question is incomplete. The complete question is :
A manufacturer believes that the cost function : 
approximates the dollar cost of producing x units of a product. The manu- facturer believes it cannot make a profit when the marginal cost goes beyond $210. What is the most units the manufacturer can produce and still make a profit? What is the total cost at this level of production?
Solution :
Given the cost function is :
Now, Marginal cost = 
So, if the marginal cost = $ 210, then the manufacturer also makes a profit and if it goes beyond $ 210 than the manufacturer cannot make a profit.
Therefore, we have to equate : 
So when x = 45, then C(x) = $ 8042.5
Therefore, the manufacturer 
to 45 units and 
This leads to a total cost of $ 8042.5
