price of a barrel in the market is $20, how many barrels will the firm produce?
b. Suppose the price in the market falls to $12 per barrel. How many barrels will this firm produce in order to maximize profits?
c. Suppose an improvement in technology shifts total costs down by $8 at every level of production. How much will the firm produce and what will profits be at a price of $20 and at a price of $12?
