4. When marginal utility begins to diminish, total utility always diminishes.
5. If a consumer is maximizing utility, she will purchase quantities of output to the point where the marginal utility per dollar spent on consumption is equal across all goods.
6. As long as the marginal utility of the last unit consumed is positive, total utility will fall if a person consumes less of a good.
7. As long as a person had to pay a positive price for a good, he would never consume to the point where his marginal utility was falling with additional consumption.
8. A person could receive a higher marginal utility from the last diamond she purchases than from the last ounce of water she purchases, yet receive less total utility from diamonds than from water.
9. If total utility from consuming five cups of cocoa is 13, 25, 35, 44, and 52 utils, respectively, the marginal utility of the fourth cup of coffee is 9.
10. If Phil says, “You would have to pay me to eat another cookie now,” it would imply that his marginal utility from consuming one more cookie now was negative.
