A. rent the room because the marginal benefit exceeds the marginal cost.
B. rent the room because the marginal benefit exceeds the average cost.
C. not rent the room because the marginal benefit is less than the marginal cost.
D. not rent the room because the marginal benefit is less than the average cost.
Answer:
A. rent the room because the marginal benefit exceeds the marginal cost.
Explanation:
Although , the original operating cost of a room per night is $100 (($10,000/100), but since there are idle capacity (empty rooms), the company will be better off by an incremental profit of $30 ($60 -$30) per room by offering to sell empty rooms for $60 per room, using a marginal (incremental ) approach.
Which law are we being asked about?
Answer: The market rate of return is 7.45%
We follow these steps to find the answer.
Here we can interpret the term 'market rate of return' as the required rate of return on the stock. We represent this as 
The current market price of stock (P₀), whose dividends are expected to grow for a constant rate is given by:

where
D = Upcoming dividend
k_{e} = required rate of return on the stock
g = constant growth rate of dividends.
Plugging in the values from the question in the formula above we get,




Answer:
For now, it is better to keep producing in house. If demand increases, Pottery Ranch must outsource some of the production.
Explanation:
Giving the following information:
The variable manufacturing overhead is charged to production at a rate of 63% of direct labor cost. The direct materials and direct labor cost per unit to make a pair of finials are $3.51 and $4.73, respectively. Normal production is 28,300 curtain rods per year.
A supplier offers to make a pair of finials for $13.20 per unit.
Fixed costs are a sunk cost, therefore it is not taken into account.
Make in house:
Unitary cost= 3.51 + 4.73 + (4.73*0.63)= $11,22
Outsource:
Unitary cost= 13.20
For now, it is better to keep producing in house. If demand increases, Pottery Ranch must outsource some of the production.
The answer is the decline stage.

Digital technologies directed to the progress of standard which is high definition then 3D HDTV and now organic light-emitting diode 3D smart HDTVs.
