a. MR = 200 4Q and MC = 6Q. Setting MR = MC yields 200 4Q = 6Q. Solving
yields Q = 20 units. The profit-maximizing price is obtained by plugging this into the
demand equation to get P = 200 - 2(20) = $160.
b. Revenues are R = (

TOTAL POINTS = 10 POINTS.
This is a Stackelberg oligopoly because there are a follower (Fiberboard Profit) and a leader
(CompositeBox).
We need first to determine the follower's reaction function.
