Andre owns a food truck that makes gourmet hamburgers, and he is looking for a way to serve more customers during the lunch rush hours of 11 a. m. to 2 p. m. His options are to hire a new employee at an hourly wage of $15; rent a Flippy robot to assist in cooking, at an hourly cost of $120; or rent a new truck that has some updates to improve efficiency, at a cost of $100 per hour. Which option gives Andre the most bang per buck if the value of the marginal product for the worker is $70 per hour, the value of the marginal product for the Flippy robot is $178 per hour, and the value of the marginal product for the updated food truck is $148 per hour
