6

B)less than average cost, greater than average cost
C)less than average cost, less than average cost

7

The firms long run output decision will be where

C)marginal revenue equals long run marginal cost
D)marginal cost equals output
8

Short run average total costs are equal to the sum of _________ and __________

A)TRUE
B)FALSE
11
