Answer:
$2,650
Step-by-step explanation:
Daniel's end-of-period spreadsheet at the end of July has $4,950 in the Balance Sheet Credit column for Accumulated Depreciation.
The end-of-period spreadsheet at the end of August has $7,600 in the Balance Sheet Credit column for Accumulated Depreciation.
Therefore the amount of the depreciation expense adjustment for the month of August is $7,600 - $4,950 = $2,650
The depreciation expense for the month would have been debited as depreciation account but credited to the accumulated depreciation account, which would have increased its balance.
