Consuelo$$ Chua, Inc., is a Columbian 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 Ms$.$ Chua that you can do a better job at aggregate planning than her current staff. She$$ said, "Fine. You do$$ 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?
