Businesswire.com reported a shortage of inventory for new and used cars during the pandemic mainly due to mass transit riders choosing to purchase a vehicle for safer transportation coupled with the ease of the transformed digital buying process along with supply chain disruptions. New vehicle sales doubled during the pandemic pushing the average price of both new and used vehicles up to an estimated $39,500 in 2021.

If using the declining-balance method, what is the depreciation expense for year 4 with an estimated life of 5 years and residual value of $19,000?
