Millco Inc., acquired a machine that cost $430,000 early in 2019. The machine is expected to last for tenth years, and its estimated salvage value at the end of its life is $63,000. Required: a. Using straight-line depreciation, calculate the depreciation expense to be recognized in the first year of the machine's life and calculate the accumulated depreciation after the fifth year of the machine's life. Depreciation expense Accumulated depreciation $ $ 36,700 183,500 b. Using declining-balance depreciation at twice the straight-line rate, calculate the depreciation expense for the third year of the machine's life. Depreciation expense $ 55,040 c. What will be the net book value of the machine at the end of its tenth year of use before it is disposed of, under each depreciation method? c. What will be the net book value of the machine at the end of its tenth year of use before it is disposed of, under each depreciation method? Net book value $ 63,000 Straight-line depreciation Declining-balance depreciation Gandolfi Construction Co. purchased a CAT 336DL earth mover at a cost of $435,000 in January 2019. The company's estimated useful life of this heavy equipment is 10 years, and the estimated salvage value is $86,000. Assume that Gandolfi Construction Co. calculated depreciation expense for the CAT 336DL earth mover on the straight-line method and reported $497,000 of net income for the year ended December 31, 2019. The company's average total assets for 2019 were $3,550,000. Required: a. Calculate Gandolfi's ROI for the year ended December 31, 2019. Return On Investment for the year ended December 31, 2019 Choose Numerator: Choose Denominator: = Net income 11 Average total assets = $ 497,000 1 $ 3,550,000 = ROI ROI 14.0% b. Calculate what Gandolfi's ROI would have been for the year ended December 31, 2019, had the company used the double- declining-balance depreciation method for the CAT 336DL earth mover. Ignore the effects of income taxes. Return On Investment for the year ended December 31, 2019 Choose Numerator: 1 Choose Denominator: = Net income 1 Average total assets $ 427,100 1 ROI ROI
