Frances sells pencils in the perfectly competitive pencil market. Her output
per day and her total cost are shown in the following table:
a. If the current equilibrium price in the pencil market is how
many pencils will Frances produce, what price will she charge, and how much
profit (or loss) will she make? Draw a graph to illustrate your answer. Your
graph should be clearly labeled and should include Frances's demand, and curves; the price she is charging; the quantity she is
producing; and the area representing her profit (or loss).
b. Suppose the equilibrium price of pencils falls to . Now how many
pencils will Frances produce, what price will she charge, and how much profit
(or loss) will she make? Show your work. Draw a graph to illustrate this
situation, using the instructions in part (a).
c. Suppose the equilibrium price of pencils falls to Now how many
pencils will Frances produce, what price will she charge, and how much profit
(or loss) will she make?
