We know that the profit from an item is the sale price minus the cost price. Thus, 1269 - 0.2x² - 830 - 398x P(x) = -0.2x² - 398x + 439 Local maxima are located at the points where the first derivative of a function are 0 P'(x) = -0.4x - 398 398 = -0.4x x = -995 There is only one maximum so the average value is -995
