Carly has the most popular costume shop in town and generates a lot of sales throughout the year. She has downloaded her 4th quarter sales and needs the data available in Excel so she can analyze her sales. Doing so will help her better manage her inventory throughout the year and during peak seasons, such as Halloween. She has asked you, her intern, for assistance in creating formulas that will help her understand the supply and demand of her costumes. The categories listed in the workbook are the top-selling categories. The shop carries over 500 types of costumes.
