A firm recently constructed a new facility at a cost of $$10$ million. Weighted$-$average accumulated expenditures for the facility were $$4$ million, actual interest was $$400,000,$ and avoidable interest was $$200,000.$ If the useful life of the facility is $40$ years and the expected salvage value is $$800,000,$ then what is the firm's depreciation expense for the first full year? $($Assume the firm is using straight$-$line depreciation.$)$

$$240,000$

$$335,000$

$$235,000$
