The Lagrangian method of optimization results in a new variable,$\lambda$,called the Lagrangian multiplier,which shows the additional to total utility from an additional unit of income.In other words,$\lambda$ expresses the:
A)the budget constraint.
B)the cost of acquiring an additional util of satisfaction.
C)the marginal utility of income.
D)the optimal level of utility.
