Answer:
5.4%
Explanation:
Several years ago the Haverford Company sold a $1,000 par value bond that now has 25 years to maturity and an 8.00% annual coupon that is paid quarterly. The bond currently sells for $900.90, and the company’s tax rate is 40%. What is the component cost of debt for use in the WACC calculation
Face value of bond = coupon amount / interest rate 
1000 = 80 / 8%
Therefore 900.9 = 80 / revised interest rate
multiply both sides by the 'revised interest rate
revised interest rate x 900.9 = 80
Hence, revised interest rate = 80  / 900.9 = 9%
Secondly if the company’s tax rate is 40%, the component cost of debt for use in the WACC calculation = kd (1 - t)
where:
kd = Cost of debt
t = tax rate
Therefore cost of debt for use in the WACC calculation = 9% (1-0.4) = 5.4%
 
        
             
        
        
        
Answer:
 $105,075
Explanation:
The computation of the operating income is shown below:
Sales (4 × 69,500)                                              $278,000
Less:Variable costs (0.95 × 69,500 + 5% × 278,000)  $79,925
Contribution margin                                                     $198,075
Less: fixed cost (13,000 + 80,000)                      $93,000
Net operating income                                                 $105,075
We simply deduct the variable cost and the fixed cost from the sales to arrive at the net operating income 
 
        
             
        
        
        
Answer:
C. straight back chairs will be overcosted
Explanation:
Miller Company makes two types of chairs. One of the chairs is a rocking chair. The other is a straight-back chair. Both chairs are made by hand. Miller Company uses a company-wide overhead rate that is based on direct labor hours to assign overhead costs to the two products. If Miller automates the production of straight-back chairs and continues to use direct labor hours as a company-wide allocation basis:
A. rocking chairs will be undercosted
B. There should be no impact on unit cost  
C. straight back chairs will be overcosted
D. rocking chairs will be overcosted.
EXPLANATION
If Miller automates the production of straight-back chairs and continues to use direct labor hours as a company-wide allocation basis then the straight back chairs will be overcosted<u> because the automation process directly implies that it no longer drives labor hours since it is no longer made by hand.</u>
Automated processes should use machine hours rather than labor hours, for the allocation of its overhead.
 
        
                    
             
        
        
        
I would say that the market economy and westward expansion promoted the institution of slavery as in the new United States whereby in order to sell more say cotton at a cheap price (the market economy) then the landowners would employ slaves for cheap labour so as to extract maximum profit from their labour.
