Final answer:
Depreciation is usually calculated on a monthly basis in business accounting, and the amount is typically rounded to the nearest dollar or cent.
Step-by-step explanation:
The concept in question pertains to the computation of depreciation, which is a business and accounting practice used to allocate the cost of tangible assets over their useful life. More often than not, depreciation is computed on a monthly basis to simplify the process and avoid the cumbersome work that computing on a daily basis would entail. In practice, companies align their depreciation calculations with their accounting periods which are typically monthly, hence, the answer is most likely to be computed on the basis of the nearest full month and, depending on company policy, to either the nearest dollar or the nearest cent. This means that businesses would round off the depreciation amount to the nearest dollar or cent at the end of each month, rather than calculating daily fluctuations.
