Problem
A. T/F/U: Your friend runs a successful coffee shop with 2 espresso machines and 4 employees. They can double their profits by renting an additional 2 espresso machines and hiring 4 employees
B. Jordan is a cost-minimizing turnip farmer, who aims to grow a certain number of turnips each year. Each additional acre of farmland that he rents costs $100,000 and produces 1000lb of turnips. Hiring an additional employee costs only $50,000. What does the marginal product of labor have to be to convince him to hire an additional employee instead of renting an extra acre of farmland?
