Check my wc Abbott Landscaping purchased a tractor at a cost of $27,000 and sold it three years later for $14,400. Abbott recorded depreciation using the straight-line method, a five-year service life, and a $3,500 residual value. Tractors are included in the Equipment account. Exercise 7-17A Part 1 Required: 1. Record the sale. (If no entry is required for a particular transaction/event, select "No Journal Entry Required" in the first account field.)
