The company is currently operating at 100% of capacity, and variable manufacturing overhead is charged to production at the rate of 70% of direct labor cost. The direct materials and direct labor cost per unit to make the lamp shades are SR4 and SR5, respectively. Normal production is 30,000 table lamps per year.
