A clothing retailer buys winter coats from one of its suppliers for $67.50. The regular selling price of the coats includes operational expenses of 46% of the selling price and a profit of 30% of the selling price. Due to an unexpected warm winter, the sales have been slow. The retailer decides to mark down this line of coats by 20% to increase sales. What is the operating profit or loss on the coats sold during the promotional sale?
