Suppose that Cathy spends all of her income on 20 units of good X and 25 units of good Y. Cathy's marginal utility from the 20th unit of good X is 9 utils, and her marginal utility from the 25th unit of good Y is 19 utils. If the price of good X is $0.50 per unit and the price of good Y is $1.00 per unit, then to comply with the rational spending rule, Cathy should:
purchase less than 20 units of good X and more than 25 units of good Y.
