During the construction of a highway bypass, earth-moving
equipment costing $40,000 was purchased for use in transporting
fill from the borrow pit. At the end of the 4-year
project, the equipment will be sold for $20,000. The schedule for
moving fill calls for a total of 100,000 cubic feet during the
project. In the first year, 40% of the total fill is
required;
in the second year, 30%; in the third year, 25%; and in the final
year, the remaining 5%. What is the units-of-production
depreciation for the fourth year for the equipment (to the
closest dollar)?
