Sharon Lee, CEO of Carla Vista 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. Sharon asked Brian Walker, Carla Vista's inventory manager, to help her understand the issue. Brian reviewed the company's records and compiled the following changes to Finished Goods Inventory (in units) for the years 2019, 2020, and 2021.
