A sales budget is given below for one of the products manufactured by the Quick Production Limited:

July : 25,000 units

August: 40,000 units

September: 65,000 units

October: 45,000 units

November: 35,000 units

December: 30,000 units

The inventory of finished goods at the end of each month must equal 20% of the next month's sales. However, on June 30 the finished goods inventory totalled only 4,000 units.

Each unit of product requires three pounds of specialized material. Since the production of this specialized material by Quick's suppliers is sometimes irregular, the company has a policy of maintaining an ending inventory at the end of each month equal to 30% of the next month's production needs. This requirement had been met on July 1 of the current year.

Required:

A budget showing the quantity of material to be purchased each month for July, August and September and in total for the quarter.
