The simultaneous equation method is The maximum possible value for the objective function is If one changes the contribution rates in the objective function of an LP A. an alternative to the corner point method. B. useful only in minimization methods. C. an algebraic means for solving the intersection of two or more constraint equations. D. useful only when more than two product variables exist in a product mix problem. E. 360. F. 480. G. 1520. H. 1560. I. the feasible region will change. J. the slope of the isoprofit or isocost line will change. K. the optimal solution to the LP is sure to no longer be optimal. L. the problem will no longer be linear.
