Wildhorse Taxi Service uses the units$-$of$-$activity method in computing depreciation on its taxicabs. Each cab is expected to be driven $160,000$ miles. Taxi $10$ cost $$31,000$ and is expected to have a salvage value of $$600.$ Taxi $10$ was driven $30,000$ miles in $2026$ and $32,000$ miles in $2027.$

$($a$1)$

Calculate depreciable cost per mile using units$-$of$-$activity method. $($Round answer to $2$ decimal places, e$.$g$.0\mathrm{.}50.)$
