On five daysof the week the average mileage is 150, but on Satur-days and Sundays the car makes 210 miles. The oper-ating expenses during June were cents per mile,this figure covering gasoline, oil, repairs, maintenance,overhead percentage, etc., but it does not include depre-ciation or interest on investment.
