If a dump truck for hauling coal has an estimated net cost of $88,000 and is expected to give service for 250,000 miles, resulting in a salvage value of $5,500, what would be the depreciation per mile? Compute the allowed depreciation amount for the same truck's usage amounting to 27,000 miles. The depreciation per mile would be $0.38. (Round to the nearest cent.) The allowed depreciation amount for the same truck's usage amounting to 20,000 miles would be $7,600. (Round to the nearest dollar.)
