In linear programming, reduced cost, or opportunity cost, is the amount by which an objective function coefficient would have to improve (so increase for maximization problem, decrease for minimization problem) before it would be possible for a corresponding variable to assume a positive value in the optimal solution. It is the cost for increasing a variable by a small amount, i.e., the first derivative from a certain point on the polyhedron that constrains the problem. When the point is a vertex in the polyhedron, the variable with the most extreme cost, negatively for minimization and positively maximization, is sometimes referred to as the steepest edge. Given a system minimize subject to , the reduced cost vector can be computed as , where is the dual cost vector. It follows directly that for a minimization problem, any non- at their lower bounds with strictly negative reduced costs are eligible to enter that basis, while any basic variables must have a reduced cost that is exactly 0. For a maximization problem, the non-basic variables at their lower bounds that are eligible for entering the basis have a strictly positive reduced cost. (Wikipedia).

In this video we cover the idea of marginal cost. This is simply the derivative of the cost function. We can roughly define marginal cost as the cost of producing one additional item. For more videos please visit http://www.mysecretmathtutor.com

Percentage Increase & Decrease - Using Multipliers | Number | Maths | FuseSchool
In this video we are going to look at how to do percentage increases and decreases, using multipliers. You should already know what percentages are, and how to find them. Example: A train ticket costing £40 is reduced by 20%. What is the price of the new ticket? 20% of 40 = 20/100 X 40
