In 1987, Herman Moore Company completed the construction of a building at a cost of $2,980,000 and first occupied it in January 1988. It was estimated that the building will have a useful life of 40 years and a salvage value of $89,400 at the end of that time. Early in 1998, an addition to the building was constructed at a cost of $745,000. At that time, it was estimated that the remaining life of the building would be, as originally estimated, an additional 30 years, and that the addition would have a life of 30 years and a salvage value of $29,800. In 2016, it is determined that the probable life of the building and addition will extend to the end of 2047, or 20 years beyond the original estimate.

Using the straight-line method, compute the annual depreciation that would have been charged from 1988 through 1997. (Round answer to 0 decimal places, e.g. 45,892.)

Annual depreciation from 1988 through 1997 $ / yr = ??????

Compute the annual depreciation that would have been charged from 1998 through 2015. (Round answer to 0 decimal places, e.g. 45,892.)
