Orange Corp. constructed a machine at a total cost of $80 million. Construction was completed at the end of 2012 and the machine was placed in service at the beginning of 2013. The machine was being depreciated over a 10-year life using the sum-of-the-years'-digits method. The residual value is expected to be $6 million. At the beginning of 2016, Orange decided to change to the straight-line method. Ignoring income taxes, what will be Orange's depreciation expense for 2016? (Do not round your intermediate calculation and round final answer to 1 decimal place.)
