Answer:
Option (b) $12,960
Step-by-step explanation:
Data provided in the question:
Cost = $90,000
Salvage value = $3,600
Useful life = 120,000 miles
Number of miles driven in 2012 = 18,000
Number of miles driven in 2013 = 32,000
Now,
Using the straight line method of depreciation
Rate of annual depreciation = [ Cost - Salvage value ] ÷ Useful life
= [ $90,000 - $3,600 ] ÷ 120,000
= $0.72 per mile
Therefore,
The depreciation expense for 2012
= Rate of annual depreciation × Number of miles driven in 2012
= $0.72 per mile × 18,000
= $12,960
Hence,
Option (b) $12,960
