Balancing utility and price suppose kate has to choose between purchasing high-definition televisions and milk. which of the following is the utility-maximizing rule that kate should follow while choosing the optimal quantities of these two goods? (note: in the answer options that follow, mu stands for "marginal utility.") (mu of milk) times (price of milk) = (mu of hdtvs) times (price of hdtvs) mu of milk = mu of hdtvs mu of milk/price of hdtvs = mu of hdtvs/price of milk mu of milk/price of milk = mu of hdtvs/price of hdtvs since milk costs little and high-definition televisions are expensive, it must follow that when people choose their optimal quantities of milk and high definition televisions to purchase, the marginal utility they receive from the last high-definition television they buy the marginal utility they receive from the last gallon of milk they buy.
