9. ChemLabs uses raw materials I and II to produce two domestic cleaning solutions, A and B. The daily availabilities of raw materials I and II are 150 and 145 units, respectively.

One unit of solution A consumes .5 unit of raw materiall and .6 unit of raw material II, and one unit of solution Buses .5 unit of raw materiall and .4 unit of raw materiaill. The profits per unit of solutions A and Bare $8 and $10, respectively. The daily demand for solution A lies between 30 and 150 units, and that for solution B between 40 and 200 units. Find the optimal production amounts of A and B.
