Hi there.
I recently learned in Social Studies that services are usually intangible services. They have value, but you cannot physically touch them.
I'm also using the process of elimination. With that, I give you my best guess:
A. Because it provides support but no tangible goods.
Hope this works out for ya!
        
                    
             
        
        
        
Answer:
As the variable cost increased by $2.10 per book so if publisher wants to start making profit at same level of production then it should increase the selling price of the book by $2.10. As the increase in cost and selling price will be same so the publisher will also start making profit at same production level. 
 
        
             
        
        
        
Answer:
False
Explanation:
The formula for equivalent units units as follows:
Opening Work in Process + Equivalent units on which the work is done - Closing Work in process = Units Transferred
Therefore, ideally,
Opening work in process - Closing work in process = Units transferred - Equivalent units on which work is done.
As adding all the cost incurred during the period to opening inventory of work in process, we get the total cost for the period, thereafter, deducting the cost allocated to closing work in process we get the value of goods produced and transferred.
<u>Therefore, above statement is false.</u>
