Which of the following quantity–price combinations would a profit-maximizing publisher choose?
(Note: If the publisher is indifferent between more than one choice, select all of the indifferent combinations.) 
Check all that apply.
300,000 copies at a price of $70
 
400,000 copies at a price of $60
 
500,000 copies at a price of $50
 
600,000 copies at a price of $40
 
Complete the third column of the previous table by computing marginal revenue. (Hint: Recall that MR=ΔTRΔQMR=ΔTRΔQ.)
True or False: At each quantity, marginal revenue is less than the price.

Use the black points (plus symbol) to graph the marginal revenue from the 100,000th, 200,000th, 300,000th, 400,000th, 500,000th, and 600,000th copy of the novel. Remember to plot from left to right and to plot between integers. For example, if the marginal revenue of increasing production from 100,000 copies to 200,000 copies were 10, then you would plot a point at (150, 10). Next use the orange line (square symbol) to graph the marginal-cost curve faced by the publisher. Finally, use the blue points (circle symbol) to graph demand at the following quantities (in thousands): 0, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1,000. 
 
The marginal-revenue and marginal-cost curves intersect at a quantity of (?)   copies.
 
On the previous graph, use the black triangle (plus symbols) to shade the area representing deadweight loss.
 
If the author were paid $3 million instead of $2 million to write the book, the publisher would (?)    the price it charges for a copy of the novel.
 
Suppose the publisher was not profit-maximizing but was concerned with maximizing economic efficiency, and the author of a novel was paid $2 million to write the book.
 
In this case, the publisher would charge ($) ?
 
for a copy of the novel and earn a profit of ( $) ?
 
(Note: If the publisher experiences a loss, be sure to enter a negative number for profit.)

On the following graph, use the orange points (square symbol) to plot the marginal-cost curve for Jane's Juice Bar. (Note: Be sure to plot from left to
right and to plot between integers. For example, if the marginal cost of increasing production from 1 vat of juice to 2 vats of juice is $5, then you
would plot e point at (1.5, 5).) Then use the purple points (diamond symbol) to plot the average-variable cost curve starting at 1 vat of juice, and use
the green points (triangle symbol) to plot the average-total-cost curve also starting at 1 vat of juice.
