Graph 17-1

-Refer to Graph 17-1, panel A. Assume the market is monopolistically competitive and in long-run equilibrium. If drawn in, the average total cost curve would be:

A) tangent to the demand curve at the market price, P^a
B) tangent to the demand curve where marginal cost intersects demand
C) tangent to the marginal revenue curve at the market price, P^a
D) tangent to the marginal revenue curve at the point where marginal cost intersects marginal revenue
