Answer:
$2,500,000
Step-by-step explanation:
Depreciation is the charge of capital expense to the P&L due to the annual wear and tear of the asset.
Units of production method depreciate an expense on the basis of the production made within a period as a percentage of total capacity of the asset.
In this flying miles are considered to the the basis for the depreciation.
As per given data
Value of Jet = $40,000,000
Total Capacity = 400,000,000 miles
Depreciable value = Cost of the Jet - Residual Value = $40,000,000 - $0 = $40,000,000
Depreciation per mile = $40,000,000 / 400,000,000 = $0.1 per mile
Flying in the year = 25,000,000 miles
Depreciation for the year = 25,000,000 x $0.1 = $2,500,000
