What is the main principle of marginal utility theory?
- AAs more is consumed of a normal good, the additional satisfaction gained increases.
- BConsumers are in equilibrium when the marginal utility gained from good X equals the price of good Y.
- CConsumers are in equilibrium when the ratio of the marginal utility of goods X and Y are equal to the ratio of their prices.
- DConsumers are in equilibrium when the total utility gained from good X is the same as gained from good Y.
