Lester Production is planning to sell 600 boxes of ceramic tile, with production estimated at 580 boxes during May. Each box of tile requires 44 pounds of clay mix and a quarter hour of direct labor. Clay mix costs $0.40 per pound and employees of the company are paid $12.00 per hour. Manufacturing overhead is applied at a rate of 110% of direct labor costs. Lester has 2,600 pounds of clay mix in beginning inventory and wants to have 3,000 pounds in ending inventory
