new flavor, the start-up cost for the new store location would be $50,000. Over the course of the next year,
operating costs for already existing locations will be $100,000. What is Jeni's opportunity cost of developing a
new ice cream flavor?
a. $150,00
0
b. $100,00
0
c. $200,00

12. Nissan manufactures sedans and pickup trucks. As one of Nissan's economists, you're in charge of ensuring
efficient management of costs. In the past, if Nissan devoted all of its resources to manufacturing sedans, it
could produce 480,000 sedans per year at one manufacturing plant. If Nissan devoted all of its resources to
manufacturing trucks, it could produce 240,000 trucks per year. A new production technique now allows Nissan
to produce either 600,000 sedans or 360,000 trucks per year. How would Nissan's production possibilities
frontier reflect this new production technique?
a. A movement along the production possibilities frontier to manufacture more
sedans.
b. A movement along the production possibilities frontier to manufacture more
trucks.
c. An inward shift of the production possibilities frontier.
d. An outward shift of the production possibilities frontier.
