a. Run OLS to determine the demand function as P = f(Q); how much confidence do you have in this estimated equation? Use algebra to invert the demand function to Q = f(P). b. Using calculus to determine dQ/dP, construct a column which calculates the point-price elasticity for each (P,Q) combination.

a. Run OLS to determine the demand
function as P = f(Q); how much confidence
do
you have in this estimated equation?
Use algebra to invert the demand function
to Q = f(P).
b. Using calculus to determine dQ/dP,
construct a column which calculates the
point-price elasticity for each (P,Q)
combination.
c. What is the point price elasticity of
demand when P=$210.00? What is the
point price elasticity of demand when
P=$173.25?
d. To maximize total revenue, what would
you recommend if the company was
currently charging P=$203.70? If it was
charging P=$173.25?
e. Use your first demand function to
determine an equation for TR and MR as a
function of Q, and create a graph of P and
MR on the vertical and Q on the horizontal
axis.
f. What is the total-revenue maximizing
price and quantity, and how much revenue
is earned there? (Round your price to the
nearest cent, your quantity to the nearest
whole unit, and your TR to the nearest
dollar.) Compare that to the TR when P =
$210.00 and P = $173.25.
