This is one of McDonald's many recent marketing moves that have led the Wall Street Journal to claim "McDonald's is Cool Asain"". That article notes that McDonald's is seeing increased visits to its stores and increased revenue. How would we expect this to affect the wages of McDonald's workers? A) Wages increase because labor demand increases B) Wages increase because labor demand decreases C) Wages increase because the supply curve of McRib sandwiches shifts to the right D) Wages increase because the labor supply curve shifts to the left 5) "Creator" was a hamburger restaurant opened in San Francisco in which the entire preparation of the hamburger was done by a machine. (The machine is shown above. A video of the machine in action can be found here.)

D) Your opportunify cost of working is negative. 7) Kristen's hobbies mostly involve hanging out with big groups of people indoors - going to concerts, visiting restaurants, and going out dancing with her tritnds.
