The company just completed a single order from Interstate Trucking for 1,800 custom seat cushions. The order was produced in three batches. Each seat cushion required 0.7 direct labor-hour. The selling price was $141.60 per unit, the direct materials cost was $106 per unit, and the direct labor cost was $14.30 per unit. This was Interstate Trucking's only order during the year.
