Exercise 7-56 (Algorithmic) Expenditures Alter Acquisition Roanoke Manufacturing placed a robotic arm on a large assembly machine on January 1, 2019. At that time, the assembly machine was expected to last another years The following information is available concerning the assembly machine. Cost, assembly machine $750,000 Accumulated depreciation, 1/1/2019 480,000 The robotic arm cost $210,000 and was expected to extend the useful life of the machine by 3 years. Therefore, the useful life of the assembly machine, after the arm replacement, is 6 years. The assembly machine is expected to have a residual value of $114,000 at the end of its useful tta. Required: 1. Prepare the journal entry necessary to record the addition of the robotic arm. 2019 Jan. 1 (Addition to assembly machine) 2. Compute 2019 depreciation expense for the machine using the straight-line method Prepare the necessary journal entry to record depreciation expense for 2019 2019 Dec. 31 Previous The robotic arm cost $210,000 and was expected to extend the useful life of the machine by 3 years.
