estimated that the building will have a useful life of $40$ years and a salvage value of $$60,000$ at the end of that time.

Early in $2009,$ an addition to the building was $4$ nstructed at a cost of $$505,000.$ 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 $$20,250.$
