ChemLabs uses raw materials I and II to produce two domestic cleaning solutions, A and B. The daily availabilities of rawmaterials I and II are 150 and 145 units, respectively. One unit of solution A consumes 0.5 unit of raw material I and 0.6unit of raw material II, and one unit of solution B uses 0.5 unit of raw material I and 0.4 unit of raw material II. Theprofits per unit of solutions A and B are $8 and $10, respectively. The daily demand for solution A lies between 30 and 150units, and that for solution B between 40 and 200 units. Find the optimal production amounts of A and B using the GraphicalMethod.
