Manders Manufacturing Corporation uses the following model to determine an optimal short-term product mix for its two products, metal (M) and scrap metal (S): Max Z = $30M + $70S Where: 3M + 2S 15 2M + 4S 18 The point where M = 2 and S = 3 would: Multiple Choice Be a feasible point. Minimize total cost. Be the optimal solution point. Lie in a corner of a graphical representation of the model. Minimize total variable cost.
