3. Following table shows the number of labor hours required to produce a digital camera and a bushel of wheat in US and South Korea. Please answer following questions referring to the table. US South Korea Total Digital Camera 100 hours 90 hours 190 hours Wheat (bushels) 5 hours 3 hours 8 hours A). If each country has a total of 9,000 labor hours to devote to the production of the two goods, please draw the production possibilities frontier for each country. Put "Digital Camera" on the horizontal axis and "Wheat" on the vertical axis. Be sure to identify the intercept values on your graphs. B). Suppose each country allocates 60% its labor hours to wheat production and 40% to the production of digital cameras. Complete the table like the one above to show each country's output of the two products. C). c. If the two countries do not trade and consume whatever they produce, identify the current production and consumption point for each country on their respective production possibilities frontiers. Label US's consumption point “C” and South Korea's consumption point, "K".
