A Company Is Planning to Manufacture a New Blender $\frac { x ^ { 2 } } { 20 }$

Multiple Choice

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.

A) R(x) = 20x + $\frac { x ^ { 2 } } { 20 }$
B) R(x) = 80x - $\frac { x ^ { 2 } } { 20 }$
C) R(x) = 80x - 20 $x ^ { 2 }$
D) R(x) = 80x - 20
