A storage tank acquired at the beginning of the fiscal year at a cost of $82,800 has an estimated residual value of $4,800 and an estimated useful life of 6 years.

Note: When calculating the depreciation rate, if the rate is not a whole number, carry out the decimal place at least six places. For example, if the straight-line rate is 33.333333%, don't round it; carry it as far as you can before doubling it for double-declining-balance method.
