Choice based on Marginal Utility per Dollar EDWARD BAHAW - Economic Principles and Their Application to Business (ABE) Quantity of hot dogs Total Utility Marginal Utility Quantity of Hamburgers Total Utility Marginal Utility 0 0 0 0 1 250 250 1 300 300 2 450 200 2 570 270 3 640 190 3 820 250 4 790 150 4 1060 240 5 900 110 5 1290 230
12. Choice based on Marginal Utility per Dollar The consumer achieves equilibrium in consumption when 4 hot dogs and 1 hamburger are consumed. EDWARD BAHAW - Economic Principles and Their Application to Business (ABE) Quantity of hot dogs Marginal Utility/Price Quantity of hamburgers Marginal Utility/Price 0 0 1 25 1 15 2 20 2 13.5 3 19 3 12.5 4 15 4 12 5 11 5 11.5
13. Choice based on Marginal Utility per Dollar If the price of hamburgers is lowered to $12, then the new marginal utility to price ratios would be as shown in the table. This shows that the consumer achieves equilibrium when 2 hot dogs and 4 hamburgers are consumed.

14. First Law of Demand Therefore as the price of hamburgers is lowered from $20 to $12, the quantity demanded increases from 1 unit to 4 units. This depicts the inverse relationship between the price of a good and the quantity demanded as represented by the demand curve in the figure.
