Answer:
B. $12,500
Explanation:
Accumulated depreciation is the cumulative depreciation of an asset up to a single point or current point in its life.
Each period, the depreciation expense recorded in that period is added to the beginning accumulated depreciation balance. Therefore when there's an entry of depreciation of an equipment, the current value is added to the previous total of the old entry. Therefore the balance of the the depreciation after current entry is the beginning balance of the depreciation plus the balance entered into the record.
In this case, the beginning balance was $10,000 and the entry was $2,500
Hence, balance of accumulated depreciation account after entry is 10000 + 2500 = $12,500
