Equipment with a cost of $240,000 has an estimated salvage value of $15,000 and an estimated life of 4 years or 15,000 hours. It is to be depreciated using the units-of-activity method. What is the amount of depreciation for the first full year, during which the equipment was used 3,300 hours?121. Larime Company purchased equipment for $40,000 on January 1, 2007, and will use the double-declining-balance method of depreciation. It is estimated that the equipment will have a 5-year life and a $2,000 salvage value at the end of its useful life. The amount of depreciation expense recognized in the year 2009 will be122. Interline Trucking purchased a tractor trailer for $98,000. Interline uses the units-of-activity method for depreciating its trucks and expects to drive the truck 1,000,000 miles over its 12-year useful life. Salvage value is estimated to be $14,000. If the truck is driven 90,000 miles in its first year, how much depreciation expense should Interline record?123. An asset was purchased for $150,000. It had an estimated salvage value of $30,000 and an estimated useful life of 10 years. After 5 years of use, the estimated salvage value is revised to $24,000 but the estimated useful life is unchanged. Assuming straight-line depreciation, depreciation expense in year 6 would be
