Revenue. The marketing research department for a company that manufactures and sells memory chips for microcomputers established the following price-demand and revenue functions. p x = 75 − 3 x Price − demand function R x = x p x = x 75 − 3 x R e v e n u e f u n c t i o n Where p x is the wholesale price in dollars at which x million chips can be sold, and R x is in millions of dollars. Both functions have domain 1 ≤ x ≤ 20 (A) Sketch a graph of the revenue function in a rectangular coordinate system . (B) Find the value of x that will produce the maximum revenue. What is the maximum revenue? (C) What is the wholesale price per chip that produces the maximum revenue?

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
