7. John works at Mcdonald's. He can spend his time there preparing burgers or chicken sandwiches. In one hour, if he spends all of his time and resources making burgers, he can make 64 burgers. In one hour, if he spends all of his time and resources making chicken sandwiches, he can make 16 chicken sandwiches. Obviously he is also allowed to split his time during that hour making either burgers or chicken sandwiches. Show John's PPF below. Remember to label the axes and endpoints. Also label the midpoint, where John spends 30 minutes making burgers and 30 minutes making chicken sandwiches. Labeling a point means listing its x- and y- coordinates
