(Round answer to 2 decimal places, e.g. 0.50.) Depreciation cost per unit $ per mile (b) Prepare a depreciation schedule assuming actual mileage was: 2027, 38,500; 2028, 31,000; 2029, 31,000; and 2030, 42,000. (Round cost per unit to 2 decimal places, e.g. 15.25 and all other answers to 0 decimal places, e.g. 5,275.)
