Heisenberg Labs uses two types of raw materials (I and II) to produce two different chemical cleaning products: Floor cleaner and kitchen cleaner. The daily availabilities of raw materials I and II are 150 and 145lbs, respectively. Producing one gallon of floor cleaner requires 0.5lb of raw material I and 0.6lb of raw material II, while one gallon of kitchen cleaner requires 0.5 lb of raw material I and 0.4lb of raw material II. The production costs are $12 per gallon for the floor cleaner and $11 per gallon for the kitchen cleaner. The sales price for the floor cleaner is $20, and $21 for the kitchen cleaner. The daily demand for floor cleaning is between 30 and 150 gallons, and for the kitchen cleaner is between 40 and 200 units. What should the optimal daily production for the floor and kitchen cleaners? Please do the following (credit is assigned at the end of each bullet): 1. Formulate a mathematical model for this problem utilizing the six-step process discussed in class 2. Utilize the graphical method to find the optimal solution 3. Solve the problem by using Excel
