Skylar runs a restaurant that sells two kinds of desserts. Skylar knows the restaurant must make at least 26 and at most 70 trays of the Fluffy Deliciousness. The restaurant must also make at least 20 and at most 42 trays of the White Chocolate Blizzards. Each tray of Fluffy Deliciousness takes 7 ounces of sugar, while each tray of White Chocolate Blizzards requires 10 ounces of sugar. The restaurant only has 700 ounces of sugar available. Suppose each tray of Fluffy Deliciousness generates $2.99 in income, each tray of White Chocolate Blizzards generates $1.97, and Skylar needs to maximize income. Let be the number of trays of Fluffy Deliciousness and let y be the number of trays of White Chocolate Blizzards. Set up the linear programming model. Maximize: z Subject to: 26 20 20 7x+10y 70 y42
