Consuelo Chua, Inc., is a disk drive manufacturer in need of an aggregate plan for July through December. The company has gathered the following data given in the tables. There are 8 hours of production per day. You manage a consulting firm down the street from Consuelo Chua, Inc., and to get your foot in the door, you have told Mr. Chua that you can do a better job at aggregate planning than his current staff. He said, "Fine. You do that, and you have a 1-year contract." To make good on your boast, you propose a new strategy. Hire 5 workers in August and 5 more in October, and subcontract to meet the rest of the demand. What will be the cost of this strategy?
