Fоrmulаte the lineаr prоgrаming mоdels. DO NOT SOLVE THEM. Be sure to clearly define each decision variable and write each constraint mathematically. A bakery makes cakes and pastries, and each product needs to go through both the baking oven and the decoration station. The oven can bake 80 pastries a day if it’s used only for pastries, or 40 cakes a day if it’s used only for cakes. The decoration station can handle 60 cakes a day if it’s focused solely on cakes, or 90 pastries a day if it’s dedicated to pastries. Each cake earns the bakery $10 in profit, while each pastry brings in $5. The goal is to figure out the best daily production plan for cakes and pastries to maximize the bakery’s profits. Clearly identify: decision variables, profit-maximization objective, oven-capacity constraint, decoration-capacity constraint, non-negativity restrictions.
