A conveyor was purchased for $40,000. Shipping and installation costs were $15,000. It was expected to last 6 years, when it would be sold for $5000 after paying $3000 for dismantling. Instead, it lasted 9 years, and several workers were permitted to take it apart on their own time for reassembly at a private technical school. How much of a gain, loss, or recaptured depreciation is there? Assume:
(a) 7-year MACRS.
(b) Straight-line.
(c) Double-declining balance with switch to straight-line.
(d) SOYD.
