In a purely competitive market, a firm will produce up to the point where the market price equals the marginal cost (MC) to maximize profit or minimize losses. At a market price of $68.10, the closest MC without going over is $68.07 for 8 units. To calculate economic profit, subtract total costs from total revenue (TR). TR at 8 units is $68.10 * 8 = $544.80. Total cost (TC) for 8 units is $51.76 * 8 = $414.08. Economic profit = TR - TC = $544.80 - $414.08 = $130.72.
