Pizza Hut produces frozen pizza products. The company makes a net income of $1.00 for each regular pizza and $1.50 for each deluxe pizza produced. Pizza Hut currently has 150 pounds of dough mix and 50 pounds of topping mix. Each regular pizza uses 1pound of dough mix and 4 ounces (16 ounces = 1 pound) of topping mix. Each deluxe pizza uses 1 pound of dough mix and 8 ounces of topping mix. Based on the past demand per week, Pizza Hut can sell at least 50 regular pizzas and at least 25 deluxe pizzas. The problem is to determine the number of regular and deluxe pizzas the company should make to maximize net income.
