Final answer:
The amount of depreciation for the first full year with 2,700 hours of usage is $113,400.
Step-by-step explanation:
To calculate depreciation using the units-of-production method, we need to find the depreciation cost per hour. The formula for depreciation per hour is (Cost - Salvage Value) / Total Estimated Hours. Plugging in the values, the depreciation per hour is ($450,000 - $30,000) / 10,000 = $42. To find the depreciation for the first full year, we multiply the depreciation per hour by the number of hours used, which is $42 * 2,700 = $113,400. Therefore, the amount of depreciation for the first full year is $113,400.
