A construction company buys a bulldozer for $25,000. The company expects the useful life of the machine to be 12 years, at which time its value will have depreciated to $7000. The company uses the declining balances method for depreciation, so the annual depreciation rate $r$ (in decimal form) is given by the formula
R=1-(S/C)^1/n
In the formula, $n$ is the useful life of the item (in years), $S$ is the salvage value (in dollars), and $C$ is the original cost (in dollars). What annual depreciation rate (in percent form) did the company use? Round your answer to the nearest tenth.
