Courtney Company uses a periodic inventory system. The following data were available: beginning inventory, 1,900 units at $20; purchases, 5,700 units at $25; operating expenses (excluding income taxes), $96,000; ending inventory per physical count at December 31, 1,200 units; sales price per unit, $50; and average income tax rate, 30%. Required: 1. Prepare income statements under the FIFO, LIFO, and weighted average costing methods. (Do not round intermediate calculations. Round your final answers to the nearest dollar amount.)
