The Hilton Skating Club used straight$-$line depreciation for a used Zamboni ice$-$resurfacing machine that cost $$49,500,$ under the assumption it would have a four$-$year life and a $$6,200$ trade$-$in value. After two years, the club determined that the Zamboni still had three more years of remaining useful life, after which it would have an estimated $$4,210$ trade$-$in value.
