Grant has 3 hours of time in all to divide between studying for a physics exam and a geology exam. Table 1 shows his estimates of the grades (on a scale of 0 to 100) that he could earn from studying a particular number of hours on each subject. If he plans on spending two hours studying physics and one hour on geology, what would be his opportunity cost of an additional hour studying physics? He now spends 3 hours on physics and 0 in geology a. 10 points on his geology exam b. 20 points on his geology exam c. 30 points on his geology exam d. 25 points on his physics exam e. 85 points on his physics exam 2. Carl is considering attending a concert with a ticket price of $35. He estimates that the cost of driving to the concert and parking there will total an additional $20. In order to attend the concert, Carl will have to take time off from his part-time job and forgo studying for an exam scheduled for the next morning.

Utopia's opportunity cost of producing 500 pounds of coffee is 1000 tons of steel e. Utopia's production must have been technically inefficient in 2004 4. Figure 1 on the next page shows the production possibilities for the US and China. Suppose each country were to only produce the good in which they have a comparative advantage.
