The demands, costs, and storage requirements for each model are summarized in the following table: It costs $60 to do the administrative work associated with preparing, processing, and receiving orders, and SuperCity assumes a 25% annual carrying cost for all items it holds in inventory.

The manager of this store wants to determine the optimal order quantity for each model of TV. a. Formulate an NLP model for this problem. b. Implement your model in a spreadsheet and solve it. c. What are the optimal order quantities? d. How many orders of each type of TV will be placed each year? e. Assuming demand is constant throughout the year, how often should orders be placed
