6. Which of the following statements is true? A) Quantities Q0 and Q1 are the utility-maximizing quantities of hoagies at two different prices of hoagies. (A)

7. In order to derive an individualʹs demand curve for salmon, we would observe what happens to the utility-maximizing bundle when we change A) the price of the product and hold everything else constant. (A)

 8. Along a downward-sloping linear demand curve, A) the marginal utility from the consumption of each unit of the good falls and the total utility from consuming larger quantities increases.  (A)

9. When a country allows trade and becomes an importer of a good,  (c) domestic producers become worse off, and domestic consumers become better off. (C)

10. The world price of a pound of T-bone steak is $9.00. Before Guatemala allowed trade in beef, the price of a pound of T-bone steak there was $12.00. Once Guatemala began allowing trade in beef with other countries, Guatemala began  (d) importing T-bone steak and the price per pound in Guatemala decreased to $9.00. (D)

12. Refer to Figure 5. If China were to abandon a no-trade policy in favor of a free-trade policy, (c) total surplus in the Chinese economy would increase. ((C)

13. Refer to Figure 6. The imposition of a tariff on carnations  (c) decreases the number of carnations imported by 200. (C)

 14. Refer to Figure 6. The amount of revenue collected by the government from the tariff is (b) $400.(B)
