In a perfectly competitive market, the profit-maximizing output could be found at point where (Price (P) = MC).
Given, MC = 2q + 200
Price (P) = $400
P = MC
2q + 200 = 400
2q = 200
q = 200 / 2
= 100
Answer: The profit-maximizing output is 100 units.
Total revenue (TR) = Price × Output
= $400 × 100
= $40,000 (Answer)
Total cost (TC) = 500 + q^2 + 200q
= 500 + 100^2 + 200 × 100
= 500 + 10,000 + 20,000
= $30,500 (Answer)
Profit = TR – TC
= 40,000 – 30,500
= $9,500 (Answer)
