Answer:

  R(x) = -0.05x^2 +80x

Step-by-step explanation:

Given the two points (x, p), the equation for the price associated with a given demand quantity can be written using the 2-point form:

  p = (p2 -p1)/(x2 -x1)(x -x1) +p1

  p = (40 -50)/(800 -600)(x -600) +50

  p = -0.05x +80 . . . . simplify

Then the revenue equation is ...

  R(x) = xp

  R(x) = -0.05x^2 +80x
