Your client, Mr$.$ Stench, is in the garbage business. He purchased an old excavation site because it has a large hole in which he can dump garbage. Mr$.$ Stench paid $$30,000$ for the site and, based on appraisals, estimates that the land site will be worth $$10,000$ when filled. He also estimates that, when filled to capacity, the hole will hold $50,000$dump$-$units,$$ and he expects to deposit somewhere between $9,000$ and $11,000$ dump$-$units per

year. He has asked you if he can depreciate the cost of the site he will use as a garbage dump. In search of your answer, consult the editorial materials in any tax service.
