Robert purchased and placed in service $100,000 of 7-year class assets on August 10 of the current year. He also purchased and placed in service $500,000 of 5-year class assets on November 15 of the current year. He does not claim any available additional first-year depreciation. If Roberts elects to use the MARCS straight line method of cost recovery on the 7-year class assets, diskuss the calculation of cost recovery for the 5-year class asset.???
