Consider a competitive firm with costs of C(q) = 64 + 4q² for q > 0, and C(0) = 0. In the long run, the minimum price at which this firm will supply a positive output, and the output it supplies at this price, are:

P = 32, q = 4

P = 48, q = 6

None of the other answers is correct.

P = 80, q= 10

P = 40, q = 5
