18) a company is planning to manufacture a new blender. after conducting extensive
market surveys, the research department estimates a weekly demand of 600 blenders at
a price of $50 per blender and a weekly demand of 800 blenders at a price of $40 per
blender. assuming the demand equation is linear, use the research department's
estimates to find the revenue equation in terms of the demand x.

  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

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

1/3 + 1/5 = 8/15.
