The revenue table describes the marginal revenue earned by a single-price monopolist. Use this information to answer the next two (2) questions. MR 14 6 -2 -10 4
Solution
From the above given table we can find the equation of the MR curve. Let us assume,
MR = a - bQ, Where a is the intercept term and b is the slope of the MR curve.
When MR = 22, Q = 1.
22 = a - b ------------------------------------------(Equation - 1)
Again, when MR = 14, Q = 2,
14 = a - 2b --------------------------------------(Equation - 2)
Solving both the equations to find a and b,
14 = 22 + b - 2b
b = 8
So, a = 22 + 8 = 30.
The equation to the MR curve is MR = 30 - 8Q.
The market demand curve is half the slope of the MR curve.
So, the market demand curve can be written as,
P = 30 - 4Q
Q = 7.5 - (1/4)P
a) Q = 7.5 - (1/4)P
