financial accounting

In recent years, Avery Transportation purchased three used buses. Because of frequent turnover in the accounting department, a different accountant selected the depreciation method for each bus, and various methods were selected. Information concerning the buses is summarized as follows.

Bus		Acquired		Cost		Salvage Value		Useful Life in Years		Depreciation  Method
1		1/1/13		$98,300		$5,300		5		Straight-line
2		1/1/13		121,000		11,700		5		Declining-balance
3		1/1/14		80,340		8,700		4		Units-of-activity

For the declining-balance method, the company uses the double-declining rate. For the units-of-activity method, total miles are expected to be 119,400. Actual miles of use in the first 3 years were: 2014, 26,300; 2015, 34,300; and 2016, 29,600.

Calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, e.g. 0.50.)
