A new electric saw for cutting small pieces of lumber in a
furniture manufacturing plant has a cost basis of $6,000 and a
10-year depreciable life. The estimated SV of the saw is zero at
the end of 10 years. Use the DB method to calculate the annual
depreciation amounts when:
(a) R = 2/N (200% DB method)
(b) R = 1.5/N (150% DB method)
