Answer:
Variable cost = $6,550
Explanation:
Variable cost is the cost incurred during the production process that changes with quantity of goods produced. For example labor, machine operating cost, and raw materials.
The other type of cost is variable cost that does not change with volume of production, but rather remains constant. For example rent, tax, and so on.
In the given instance the costs that are variable are cost of labor, cost of electricity to run printing presses, and cost of ink for paper.
Monthly mortgage and property tax are fixed cost that must be paid regardless of production volume.
variable cost = $5,500 + $800 + $250
Variable cost = $6,550

Answer:
the required rate of return i r=0.13%
Explanation:
In order to calculate the required rate of interest in the case of a perpetual preferred stock we will use the following formula:
P(p) = D(p) / r
where P(p) is the preferred price of the stock, D(p) is the preferred dividend price and r is the required rate of interest.
This gives us the following values:
30 = 4 / r
r = 4 / 30
r = 0.13%
 
        
             
        
        
        
With stocks of 8% for A and 16% for B, The global minimum variance is given as 10.5 percent
<h3>How to solve for the variance</h3>
The expected return of the stock for the country a is given as 0.05
The Weight of this country's stock market WA  = 0.5
The expected return of the stock for the country a is given as 0.16
The Weight of this country's stock market Wb  = 0.5
Expected Return of the portfolio can be calculated as
 = (WA x RA) + (WB * RB)
Expected Return of the portfolio = (0.5x 0.05 ) +(0.5*0.16)
= 0.105
= 10.5%
