Hannibal Steel Company has a Transport Services Department that provides trucks to haul ore from the company's mine to its two steel mills-the Northern Plant and the Southern Plant. Budgeted costs for the Transport Services Department total $193,100 per year, consisting of $0.21 per ton variable cost and $143,100 fixed cost. The level of fixed cost is determined by peak-period requirements.

During the year, the Transport Services Department actually hauled the following amounts of ore for the two plants: Northern Plant, 122,000 tons; Southern Plant, 53,200 tons. The Transport Services Department incurred $360,000 in cost during the year, of which $52,500 was variable cost and $307,500 was fixed cost. Required: 1.
