Answer:
open an new office because the expected marginal benefit ($12.5 million over 5 years) is greater than the estimated marginal cost ($7 million)
Explanation:
The computation is shown below;
Given that 
Total marginal benefit = 12.5 million
And, the Total marginal cost = 7 million
Based on the above information 
We can see that the new office should be opened as the marginal benefit would be more than the marginal cost 
Therefore the first option is correct
And, the rest of the options would be incorrect
 
        
             
        
        
        
An example of a study that has a false correlation caused by a lurking variable is " research scientist examines the influence of diet and exercise on a an individual's blood pressure."
<h3>What is a lurking variable in a study?</h3>
Lurking variable is known to be a kind of a  variable that is said not be the explanatory variable nor can it be called the response variable but it is one that is seen to have a relationship (e.g. correlation) with the response and that of the  explanatory variable.
Note that A lurking variable is one that can be falsely identify as a strong relationship that exist between variables or it is one that often hide the true relationship. 
Hence, An example of a study that has a false correlation caused by a lurking variable is " research scientist examines the influence of diet and exercise on a an individual's blood pressure."

When you see a journal entry that leads to a debit of Raw Materials and a credit of Accounts Payable, this is a<u> C. purchase of materials. </u>
<h3 /><h3>What happens when materials are purchased?
</h3>
As materials are an asset, the raw materials account will be debited to show that raw materials are increasing. 
If the Accounts Payable is credited, it means that it is increasing as well because it is a liability. The transaction was therefore done by buying the materials on credit. 
In conclusion, option C is correct.

Answer:
Decrease; Increase
Explanation:
When there is a decline in the marginal productivity of low skilled workers, it results in a decline or decrease in the demand for low skilled workers. Marginal productivity is the extra output gained from adding one unit of labour. Thus, if low skilled workers are added to increase marginal productivity, but then reaches the point of decline, the demand or the need for those low skilled workers reduces. The reduction or decrease in the demand for these low skilled workers then lead to an increase in number of unemployed workers as those unskilled workers becomes jobless.
 
        
             
        
        
        
Answer:
$51,588.70
Explanation:
The computation of the total amount of interest revenue is shown below:-
Annual lease payments = Fair value of Equipment ÷ PV factor of $1 annuity due
= $323,400 ÷ (1 + (1 - (1.08)^-4) ÷ 0.08)
= $323,400 ÷ 4.31213
= $74,997.74
Now,
Total interest revenue = Gross lease payments receivable - Fair value
= $74,997.74 × 5 - $323,400
= $374,988.70 - $323,400
= $51,588.70
