10.1 Ella Maksimov is CEO of her own marketing firm. The firm recently moved from a strip mall in the suburbs to an office space in a downtown building, in order to make the firm’s employees more accessible to clients. Two new clients are interested in using Ella’s advertising services but both clients are in the same line of business, meaning that Ella’s company can represent only one of the clients.

Ella estimates the cost of the services requested by Pampered Pooches to be

$83,000. Delightful Dogs is interested in hiring Ella to produce mass mailings and web ads. Delightful will pay Ella $94,000 for these services and Ella estimates the cost of these services to be $47,000. Identify any relevant costs, relevant revenues, sunk costs, and opportunity costs that Ella Graham has to consider in making the decision whether to represent Pampered Pooches or Delightful Dogs.
