A business owns multiple motor vehicles. The accumulated depreciation of all the motor vehicles is recorded in one Accumulated Depreciation account. The balance of Accumulated Depreciation at 1 July 2016 was $40,000CR. The balance of Accumulated Depreciation at 30 June 2017 was $30,000CR. The Depreciation expense for the year ended 30 June 2017 was $4,000DR. The business sold one of the motor vehicles during the financial year ending 30 June 2017. Using the above balances, calculate the accumulated depreciation of the motor vehicle that was sold.

(You may assume that apart from these transactions no other movements in the Accumulated Depreciation account were made and that any reduction in the balance of the Accumulated Depreciation account is attributable to the sale of that vehicle.)
