  • Economics, Chapter 10, Problem 5P , additional homework tip  6is the price of good Y.

Marginal Utility: It is defined as the change in the total utility due to a change in the additional unit of a good. It may be diminishing, increasing, or constant.

Maximizing utility principle: Maximizing utility in the case of two goods state that the equilibrium level of consumption of two goods for a consumer is achieved when the Marginal Utility per dollar of two goods are equal, provided the marginal utility of money is constant. This means that the following conditions must be fulfilled:
