A firm in a perfectly competitive market sells its output at ₦50 per unit. If its average total cost is ₦38 and it produces 200 units, what is its total profit?

Profit per unit = Price − Average Total Cost = ₦50 − ₦38 = ₦12. Total profit = ₦12 × 200 = ₦2,400. Option A (₦7,600) is the total cost, option C (₦10,000) is total revenue, and option D is a plausible miscalculation. The correct answer is ₦2,400.
