The minimum number of workers required to manufacture products A, B, and C is constrained as follows: 5A -|- 103 + 50' 2 455 (Workers) At optimal solution, A = 15, B = 35, and U = 5: a} How many workers were used? l:| b] By how many is the minimum number of workers exceeded? D C) Is this a binding constraint? 0 No. Because it has neither slack nor surplus at optimal solution. D Yes. Because it has a slack at optimal solution. D Yes. Because it has either a slack or surplus at optimal solution. C) No. Because it has a slack at optimal solution. C} No. Because it has a surplus at optimal solution. D Yes. Because it has no surplus at optimal solution. a) In determining the number of young (Y), middle aged (M) and the elderly (E) to test with a new vaccine, a medical team concluded that the total number of other subjects should be no less than 55% of middle- aged subjects. Which of the following best models this constraint? OM 2 0.55(Y + E) OM > 0.55(Y + M + E) OM Y + E b) Below is a randomly chosen constraint from the list above. To input this into a software (like Excel), enter your input values for the coefficients in the answer boxes. M
