Marigold Corp. purchased a delivery truck for $30,400 on January 1, 2020. The truck has an expected salvage value of $2,400, and is expected to be driven 100,000 miles over its estimated useful life of 8 years. Actual miles driven were 14,700 in 2020 and 12,600 in 2021. Calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, e.g. 0.50) Depreciation expense $ per mile Compute depreciation expense for 2020 and 2021 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 ploces, e.s. 0.50 and depreciation rate to 0 decimal places, eg. 15\%. Round final answers to O decimal ploces, eg. 2, 125.) Assume that Marigold uses the straight-line method. Prepare the journal entry to record 2020 depreciation. (Credit account titles ore outomatically indented when amount is entered. Do not indent manually. If no entry is required, select "No Entry" for the account titles and enter 0 for the amounts. Round answers to 0 decimal places, es. 2,125.) Assume that Marigold uses the straight-line method. Show how the truck would be reported in the December 31,2020 , balance sheet. (Round answers to 0 decimal places, eg. 2,125.)
