A firm called Altobella Vineyard produces Concord grapes in a perfectly competitive market in which monthly demand is given by the equation Q = 1800 - 16P and monthly supply by the equation Q = -660 + 14P, where P is the price per crate of grapes and quantities are in crates per month.
Suppose long-run entry into this grape market forces Altobella to produce at the minimum average total cost. What level of output will Altobella produce?
