Leah is in the market for a digital instant print camera. Three brands (Polaroid, Kodak, and Fujifilm) are available. A linear utility function represents her preference for a digital instant print camera. Three attributes are relevant to her decision (price, durability, and built-in battery life). On a 1-7 scale (7 being the most expensive for price, and 7 being the best for the other two attributes), the levels for each brand is:

Polaroid (Price = 4, Durability = 5, Battery life = 2)

Kodak (Price = 2, Durability =3, Battery life = 3)

Fujifilm (Price = 3, Durability = 4, Battery life = 4)

She feels durability is twice as important as either price or battery life. She also thinks price and battery life are equally important. What is Leah's choice?
