35. On January 1, 2005, 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 2010, 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 2007, under the double-declining-balance method. (Show your work.)
36. Bob Quinn is in the gravel business and has engaged you to assist in evaluating his company, Quinn
Gravel Company. Your first step is to collect the facts about the company’s operations. On January 3,
2010, Bob purchased a piece of property with gravel deposits for $3,155,000. He estimated that the
gravel deposits contained 4,700,000 cubic yards of gravel. The gravel is used for making roads. After
the gravel is gone, the land, which is in the desert, will be worth only about $100,000.
The equipment required to extract the gravel cost $726,000. In addition, Bob had to build a small
frame building to house the mine office and a small dining hall for the workers. The building cost
$76,000 and will have no residual value after its estimated useful life of ten years. It cannot be moved
from the mine site. The equipment has an estimated useful life of six years (with no residual value) and
also cannot be moved from the mine site.
Trucks for the project cost $154,000 (estimated life, six years; residual value, $10,000). The trucks, of
course, can be used at a different site.
Bob estimated that in five years all the gravel would be mined and the mine would be shut down.
During 2010, 1,175,000 cubic yards of gravel were mined. The average selling price during the year
was $1.33 per cubic yard, and at the end of the year 125,000 cubic yards remained unsold. Operating
expenses were $426,000 for labor and $116,000 for other expenses.
a. Prepare adjusting entries to record depletion and depreciation for the first year of operation (2010).
Assume that the depreciation rate is equal to the percentage of the total gravel mined during the year,
unless the asset is movable. For movable assets, use the straight-line method. (Omit explanations.)
