4. Suppose that the demand function for price increases for the firm in Problem 6 (text page 455) shifts to

Q* = 150 - 30P.

(a) Draw a figure showing the best level of output, price, and profits per unit and in total.

(b) Has the price of the firm changed or remained the same? Why?

Including screenshot of Problem 6 for reference since it is mentioned in this question but I only need help with problem 4!

Joh estimated that the demand function facing the firm he threate for price increases and price declines from the town. Joe prevailing price are, respectively, John that town, thu Q =210- 30P and Q' =90 - 10P cartel.
