Just C for this question above ^

Windsor Company constructed a building at a cost of $2,376,000 and occupied it beginning in January 2001. It was estimated at that time that its life would be 40 years, with no salvage value. In January 2021, a new roof was installed at a cost of $324,000, and it was estimated then that the building would have a useful life of 25 years from that date. The cost of the old roof was $172,800.

2) What amount of depreciation should be charged for the year 2021?

Depreciation for the year 2021 (Assume the cost of the new roof is debited to accumulated depreciation - building)?

Bonita Corporation purchased a new machine for its assembly process on August 1, 2020. The cost of this machine was $139,200. The company estimated that the machine would have a salvage value of $21,300 at the end of its service life. Its life is estimated at 5 years, and its working hours are estimated at 22,500 hours. Year-end is December 31. Compute the depreciation expense under the following methods. Each of the following should be considered unrelated. (Round depreciation rate per hour to 2 decimal places, eg. 5.35 for computational purposes. Round your answers to decimal places, e.g. 45,892.) (a) Straight-line depreciation for 2020 $ 9825 (b) Activity method for 2020, assuming that machine usage was 800 hours $ 4192 (c) Sum-of-the-years'-digits for 2021 31440 (d) d Double-declining balance for 2021 $ 46400 Touthoold d Modin
