Output = 5

Explanation:

As per the data given in the question,

Output per firm:

Marginal cost = Average total cost

MC = ATC (Since in long run each type of firm is earning zero economic profit)

(49 + q^2) : q = 2q

49 + q^2 = 2q^2

49 = q^2

q = 7

Average total cost = (49 + 49) : 7

= 98 : 7

= 14

Hence, Price = min ATC = MR = 14

Market quantity (Q)

= 49 - 14

= 35

Number of firms

= Total quantity : Output per firm

= 35 : 7

= 5
