Solution:
Using the units-of-production method,
Depreciation expense, year 1 = Equipment cost x (Units produced, year 1 / Total production over asset life)
= $876,000 x (272,000 / 1,070,000)
= $222,684.11 ~ $222,684
The production unit is a method for assessing the value of an asset over time. It becomes useful if the value of an asset is closer to its production unit than the number of years it is used.
