To maximize profit, the firm should produce at the quantity where marginal cost equals marginal revenue, which is the market price of $8 in a perfectly competitive market. From the table, we can see that at an output of 300 units, the variable cost is $960, and the total cost is $1,960. Therefore, the firm's total revenue at 300 units will be $8 × 300 = $2,400.

Profit = Total Revenue - Total Cost

Profit = $2,400 - $1,960 = $440

Therefore, the firm's profit is $440.
