Assignment:
Elasticity and Revenue
Suppose that q = 500 - 2p units of a certain commodity are demanded when p dollars per unit are charged, for 0<=p<=250.
a) Determine where the demand is elastic, inelastic, and of unit elasticity with respect to price.
b) Use the results of part (a) to determine the intervals of increase and decrease of the revenue function and the price at which revenue is maximized.
c) Find the total revenue function explicity and use its first derivative to determine its intervals of increase and decrease and the price at which revenue is maximized.
d) Graph the demand and revenue functions.
Provide complete and step by step solution for the question and show calculations and use formulas.
