11. On January 1, 2009, Town Spa Pizza purchased for $16,000 a delivery truck that will be driven an
estimated 100,000 miles. The truck has an estimated useful life of ten years and an estimated residual
value of $5,000. Calculate the following amounts: (a) depreciation expense for 2013, under the
production method (assume that 17,000 miles were driven that year); (b) the accumulated depreciation
after the truck has been used for five and one-half years, under the straight-line method; and (c)
depreciation expense for 2011, under the double-declining-balance method. (Show your work.)
12. On January 1, 2009, Tipton’s Pizza purchased for $48,000 a delivery truck that will be driven an
estimated 120,000 miles. The truck has an estimated useful life of eight years and an estimated
residual value of $12,000. Calculate the following amounts: (a) depreciation expense for 2013, under
the production method (assume that 17,000 miles were driven that year); (b) the accumulated
depreciation after the truck has been used for five and one-half years, under the straight-line method;
and (c) depreciation expense for 2011, under the double-declining-balance method.
13. Suppose an accounting intern mistakenly calculated depreciation expense on the Land account. She
assigned it a 50-year life and a residual value of $10,000,000. Using the cost of the land (assume it was
$811,000,000) and the straight-line method of depreciation, discuss the dollar effect of this error on
pretax earnings and total assets.
