Daiso Manufacturing makes a product called Super. The relevant range of operations is between 2,500 units and 10,000 units of Super per month. Total cost per unit costs at two activity levels are as follows: 5,000 units at $16.50 per unit; 7,500 units at $13.00 per unit. Determine the cost formula that expresses the behavior of Daiso's total costs: OY= $40,000 + $9X OY= $60,000 + $5X Y = $45,000+ $4X OY= $52,500 + $6X
