Answer:
$0.25 per mile
Step-by-step explanation:
The computation of the depreciation expense per mile under units-of-activity method is shown below;
= (Purchase cost - expected salvage value) ÷ estimated driven miles
= ($26,000 - $1,000) ÷ 100,000 miles
= $0.25 per mile
Hence, the depreciation expense per mile under units-of-activity method is $0.25 per mile
