volve more than one independent (explanatory) variable.  for example, consider the following sales (q) function of a firm that depends on the price of the product (p) and levels of advertising expenditures (a): 푸 = 풇 (푷,푨) 3.2.3. partial derivatives & multivariate optimization: the first-order condition 9 to determine the marginal effect of each variable, we take the first derivative of the function with respect to each variable separately, treating independent the remaining variables as constants. this process, known as taking partial derivatives, is denoted by replacing 풅 with ∂. example: consider the following explicit relationship: 푸 = 풇 (푷,푨) = ퟖퟎ푷 − ퟐ푷ퟐ − 푷푨 − ퟑ푨ퟐ + ퟏퟎퟎ푨 (where a is in thousands of dollars) determine the values of the independent variables that maximize the objective function? and the sales volume? cont….. 10 to determine the values of the independent variables that maximize the objective function, we …
