2. On January 1, Lakewood Cranes purchased a crane for $230,000. Lakewood expects the crane to remain useful for eight years (800,000 lifts) and to have a residual value of $30,000. The company expects the crane to be used for 80,000 lifts the first year. Read the requirements. a. Compute the first-year depreciation expense on the crane using the straight-line method. Begin by selecting the formula to calculate the company's first-year depreciation on the crane using the straight-line method. Then enter the amounts and calculate the depreciation for the first year. 1+1+=Straight-linedepreciation= b. Compute the first-year depreciation expense on the crane using the units-of-production method. Before calculating the first-year depreciation on the crane using the units-of-production method, calculate the depreciation expense per unit. Select the formula, then enter the amounts and calculate the depreciation per unit. (Round depreciation per unit to two decimals, XX.) \begin{tabular}{cccc} () & ()+1 & = Depreciation per unit \end{tabular} Now, select the formula, enter the amounts, and calculate the company's first-year depreciation on the crane using the units-of-production method. (Round depreciation expense to the nearest whole dollar.) c. Compute the first-yctir and second-year depreciation expense on the crane using the double-declining-balance method. Begin by selecting the formula to calculate the company's first-year and second-year depreciation on the crane using the double-declining-balance method. Then enter the amounts and calculate the depreciation for the first year. Finally, enter the amounts and calculate the depreciation for the second year. (Enter " 0 " for items with a zero value. Do not round the interim calculation. Round depreciation expense to the nearest whole dollar.)
