Suppose there are two countries, Capriland and Melodia. Both countries produce two goods, pianos and cars. Furthermore, assume that both countries have linear production possibility frontiers (PPFs). The following table provides information about the amount of labor necessary to produce one piano or one car in each of these two countries. Assume that Capriland and Melodia both have a total of 120 hours of labor available to devote to the production of pianos and cars. (Hint: put pianos (P) on the vertical axis and cars (C) on the horizontal axis as your work the various parts of this problem.)

a. Given the above information, write an equation that represents Capriland's PPF. In your equation pianos should be abbreviated as P and cars should be abbreviated as C.
