Rankine estimated that the useful life of the building was 30 years, with no residual value. a. Calculate annual depreciation expense using the straight-line method. ${#1} b. Calculate depreciation for the first and second year using the double-declining-balance method. Round to the nearest whole dollar amount. Use rounded answers in subsequestion calculations. Year 1 ${#2} Year 2 ${#3} c. Assume that in the third year, Rankine changed its estimate of the useful life of the building to 25 years.
