The manager of Parton's Pottery Company believes that the company will sell 800 place settings of pottery dinnerware next month. She expects to have 100 place settings in finished goods inventory at the beginning of the month and would like to have 200 place settings in ending inventory. Each place setting requires three pounds of clay. The manager expects to have 700 pounds of clay on hand at the beginning of the month, but she would like to decrease ending inventory to 600 pounds.
How many pounds of material will need to be purchased to meet these requirements?
