Answer:
$1,284
Step-by-step explanation:
The computation of the depreciation expense is shown below
= (Cost of diesel-powered tractor - estimated residual value) ÷ (useful operating life)
= ($208,140 - $2,700) ÷ ($48,000 hours)
= ($205,440) ÷ ($48,000 hours)
= $4.28 per hour
Now for the month, it would be
= Operated hours in a month × depreciation per hour
= 300 hours × $4.28
= $1,284
