Hannibal Steel Company has a Transport Services Department that provides trucks to haul ore from the company's mine to its two steel millsthe Northern Plant and the Southern Plant. Budgeted costs for the Transport Services Department total $200,100 per year, consisting of $0.18 per ton variable cost and $150,100 fixed cost. The level of fixed cost is determined by peak-period requirements. During the peak period, the Northern Plant requires 51% of the Transport Services Department's capacity and the Southern Plant requires 49%.

During the year, the Transport Services Department actually hauled 122,000 tons of ore to the Northern Plant and 67,700 tons to the Southern Plant. The Transport Services Department incurred $376,000 in cost during the year, of which $52,900 was variable cost and $323,100 was fixed cost.
