A sales budget is given below for one of the products manufactured by the OMI Co$.$: January $30,000$ units February $40,000$ units March $65,000$ units April $45,000$ units May $35,000$ units June $30,000$ units The inventory of finished goods at the end of each month must equal $30\%$ of the next month's sales. However, on December $31$ the finished goods inventory totaled only $4,500$ units. Each unit of product requires four pounds of specialized material. Since the production of this specialized material by OMI's suppliers is sometimes irregular, the company has a policy of maintaining an ending inventory at the end of each month equal to $25\%$ of the next month's production needs. This requirement had been met on January $1$ of the current year. Prepare a budget showing the quantity of material to be purchased each month for January, February, and March and in total for the quarter.
