Jim's diner is just about to open in Memphis, Tennessee. However, Jim is trying to decide whether he wants to offer Coke or Pepsi soda products. He determines that, to offer either product, he will have to spend $1,800 in sunk costs to purchase and install the appropriate paraphernalia, e.g., a large Coca-Cola or Pepsi sign out front. Ultimately, he chooses to offer Coke products and agrees to pay Coke 5 cents per ounce of Coke sold for the right to use its product. After Jim makes the investments specific to his soda choice, Coke returns and asks for a fixed (one-time) fee in addition to the 5 cents per ounce. What is the most Jim should be willing to pay?
