Suppose that you supply bottled water in a competitive market and that you are producing the profit-maximizing quantity of bottled water. If you can sell your water at $2 a bottle and you currently employ five workers at a wage of $50 a day, what is the value of the marginal product of the last worker you hired? What is the marginal product of that worker?
