The profit per lamp is $6, so the selling price is $120 (wholesale cost) + $6 = $126. The profit made on each lamp is $126 - $120 = $6. To find out how many lamps are in the shipment, divide the total profit by the profit per lamp: $192 (selling price) - $120 (wholesale cost) = $72 total profit. Therefore, $72 (total profit) ÷ $6 (profit per lamp) = 12 lamps in the shipment.
(192 - 120) / 6 = 121212 lamp
