Wayne enterprises is about to begin the production of a new product. The manager of the department that produces one of the components wants to know how often the machine used to produce the item will be available for other work. The machine will produce the item at a rate of 300 units a day. Eighty units will be used daily in assembling the final product. Assembly will take place five days a week, 50 weeks a year.
