The Vintage Restaurant, on Captiva Island near Fort Myers, Florida, is owned and operated by Clarita Quiones. The restaurant just completed its third year of operation. During that time, Clarita sought to establish a reputation for the restaurant as a high-quality dining establishment that specializes in fresh seafood. Through the efforts of Clarita and her staff, her restaurant has become one of the best and fastest-growing restaurants on the island. To better plan for future growth of the restaurant, Clarita needs to develop a system that will enable her to forecast food and beverage sales by month for up to one year in advance. Table 15.17 shows the value of food and beverage sales ( $1000 s) for the first three years of operation.
