unknown quantities of each. If the marginal utility of the last unit of X consumed is less than the marginal utility from the last unit of Y, then how should the consumer alter the quantities of X and Y to reach optimal consumption? (Assume the consumer is currently spending all income.) If MUX IPX<MUY IP4, If you want to learn more check out What is the descent with modification?
