On July 1, Hartford Construction purchases a bulldozer for $228,000. The equipment has a 9-year life with a residual value of $16,000. Hartford uses the units-of-output method depreciation, and the bulldozer is expected to yield 26,500 operating hours. Required:
(a) Calculate the depreciation expense per hour of operation.
(b) The bulldozer is operated 1,250 hours in the first year, 2,755 hours in the second year, and 1,225 hours in the third year of operations. Journalize the depreciation expense for each year.

a. Depreciation expense per hour:

= (Cost - salvage value) / Expected operating hours

= (228,000 - 16,000) / 26,500

= $8 per hour

b. First year depreciation:                                      Second year depreciation:

= 1,250 * 8                                                                  = 2,755 * 8

= $10,000                                                                   = $22,040

Third year depreciation:

= 1,225 * 8

= $9,800
