A Research scholar researching the market for fresh cow milk assumes that Qt= f(Pt, Y, A, N, Pc) where Qt is the quantity of milk demanded, Pt is the price of fresh cow milk, Y is average household income, A is advertising expenditure on processed pocket milk, N is population and Pc is the price of processed pocket milk.

1. What does Qt= f (Pt, Y, A, N, Pc) mean in words?
2. Identify the independent variables.
3. Make up a specific form for this function. (Use your knowledge of Economics to deduce whether the coefficients of the different independent variables should be positive or negative.)
