A company is about to begin production of a new product. The manager of a department that is asked to produce one of the

components wants to know if there is enough machine time available. The machine will produce the item at a rate of $300$ units a day.

Eighty$-$five units will be used daily in assembling the final product. The company operates five days a week, $50$ weeks a year. The

manager estimates that it will take almost a full day to get the machine ready for a production run, at a cost of $$280.$ Inventory holding

cost will be $$15$ per unit per year.
