On September 27, Nichols Florists traded in its old delivery van for a new one, which cost $ 15,000. Nichols got a trade-in allowance of $ 500 on the old van and paid the difference in cash. The property and equipment record shows the following: cost (of old van), $ 12,000; accumulated depreciation as of last December 31, $ 9,500; monthly depreciation, $ 200. Assuming that this exchange has “commercial substance,” make entries in general journal form to record the depreciation of the old van to date and to record the trade- in and purchase of the new van.
