Referring to the book Microeconomic Theory: Basic Principles and Extensions by Nicholson and Snyder reads A person prefers 1 ounce of cream and 8 ounce of coffee, if Y is cream and X is coffee then why 8 is with Y in function? as below
utility=U(x,y)= min(x,8y)
What is economic (or mathematical) logic? you can also recommend a book that deals with this confusion. Thanks
