A machine that caps soda bottles was purchased September 1, 2020 for $50,000; estimated useful life of 6 years and salvage value of $6,000. It is also estimated that the machine could cap a total of 350,000 bottles over its entire life. Calculate depreciation expense under the following independent assumptions: 1. Straight line depreciation, for the year ended Dec. 31, 2020. 2. Double declining balance depreciation for the year ended Dec. 31, 2020 and 2021. 3. Units of production depreciation for 2020 assuming 34,000 bottles were actually capped between September 1, 2020 and December 31, 2020.
