Pat and Kris are roommates. They spend most of their time studying, but they leave some time for their favorite activities: making pizza and brewing root beer. Pat takes 4 hours to brew a gallon of root beer and 2 hours to make a pizza. Kris takes 6 hours to brew a gallon of root beer and 4 hours to make a pizza.
a. What is each roommate’s opportunity cost of making a pizza? Who has the absolute advantage in making pizza? Who has the comparative advantage in making pizza?
b. If Pat and Kris trade foods with each other, who will trade away pizza in exchange for root beer?
c. The price of pizza can be expressed in terms of gallons of root beer. What is the highest price at which pizza can be traded that would make both roommates better off? What is the lowest price? Explain.
问题C我怎么也想不明白，需要要机会成本解决的经济问题，请大家帮忙哦，多谢！

1、 Pat 的机会成本是0.5加仑沙士一个批萨，Kris是0.667加仑沙士。做批萨，Pat具有绝对和相对优势。
2、 Kris将付出所有沙士，交换Pat的批萨。
3、 在交换中，Kris所能接受的最高价值是每个批萨0.667加仑沙士，高于这个价格，他就不如自己烤批萨了。所以这是最高价。而Pat能接受的最低价是0.5加仑沙士一个批萨，低于这个价格，他也会自己去酿沙士。因此，交换会在0.667-0.5加仑沙士换一个批萨之间进行。
以上是仅仅考虑生产的时间成本，不考虑物料成本。
Pat: Cost of brewing a gallon of root beer = 2 pizzas
Cost of making a pizza = 1/2 gallon of root beer
Kris: Cost of brewing a gallon of root beer = 1.5 pizza
Cost of making a pizza = 2/3 gallon of root beer
