In Kessy’s old kitchen, he could bake 10 cookies or mix 15 glasses of lemonade in a day. Now he has a bigger oven and refrigerator. a. First, draw Kessy’s initial PPF assuming constant opportunity cost between cookies and lemonade. Label it PPF1. [For this question, let cookies be illustrated on the horizontal axis.] b. Given PPF1, what is the opportunity cost of producing more cookies? In other words, how much lemonade must Kessy sacrifice to produce, say, one more cookie? c. Next, draw Kessy’s new PPF (label it PPF2) after he receives the new applicances.
