consider the following LP problem, in which X and Y denote the number of units of products X and Y to produce, respectively: Maximize = 54x+ $5y subject to constraints x+2y?@ @10 (labor variable, in hours) 6x+6y? 36 (material available, in pounds) 8x+4y ? 40 (storage availabe, in sq feet) x,y ? 0 (nonnegativity) calculate and explain what happens to the optimal soluton for each of the following situations. A. you acquire 2 additonal pounds of material B. you acquire 1.5 additonal hours of labor C. you give up 1 horu of labor and get 1.5 pounds of material D. the profit contributions for both products x and y are changed to $4.75 each
