The truck has an expected salvage value of $1,000, and is expected to be driven 100,000 miles over its estimated useful life of 5 years. Actual miles driven were 12,000 in 2017 and 10,000 in 2018. Calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, e.g. 0.52.) Depreciation expense per mile Compute depreciation expense for 2017 and 2018 using (1) the straight-line method, (2) the units-of-activity method, and (3) the double-declining-balance method. (Round depreciation cost per unit to 2 decimal places, eg. 0.50 and depreciation rate to 0 decimal places, e.g. 15%. Round final answers to 0 decimal places, eg. 2,125.)
