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

Answer:
6.5%
Explanation:
Data given in the question
Beta of the stock = 0.9
Expected return = 9%
A risk-free asset = 4%
By considering the above information, the expected return on a portfolio is
= Risk - free asset × equally basis + expected rate of return × equally basis
= 4% × 50% + 9% × 50%
= 2% + 4.5%
= 6.5%
Since we have to find out the expected return on equally invested so we considered the risk free asset and the expected rate of return
Therefore we ignored the beta of the stock
