Donna Clark, CEO of Pharoah Industries, is concerned about the recent volatility in the company's operating income. She believes that since the number of units sold has been fairly stable over the past three years that operating income also should have been stable. Donna asked Kenneth Garcia, Pharoah's inventory manager, to help her understand the issue. Kenneth reviewed the company's records and compiled the following changes to Finished Goods Inventory (in units) for the years 2019, 2020, and 2021. Year Beginning inventory Production Sales Ending inventory 2019 1,000 40,000 (39,000) 2,000 2020 2.000 38.000 (39,500) 500 2021 500 40.000 (39,500) 1.000 Kenneth also gathered the 2019 income statements prepared using absorption costing and variable costing, which follow. $ 5,070.000 Income Statement-Absorption Costing Sales Cost of goods sold Units in beginning inventory Units sold from current year production Total cost of goods sold Gross margin Selling expense Operating Income (93,000) (3.534,000) (3.627.000) 1.443.000 (630,000) 813.000 $ Income Statement-Variable Costing Sales Variable production expenses Variable selling expenses Contribution margin Fixed manufacturing expenses Fixed selling expenses Operating income $ 5.070,000 (2.145,000) (273,000) 2,652,000 (1,520.000) (357,000) S S 775.000 Compute the unit product cost for 2019, 2020, and 2021 for variable and absorption costing.
