Exercise 9

For most products, higher prices result in a decreased demand, whereas lower prices result in an increased demand. Let
Assume that a firm accepts the following price-demand relationship as being realistic:
where p must be between $20 and $70.
a. How many units can the firm sell at the $20 per-unit price? At the $70 per-unit price?
b. Show the mathematical model for the total revenue (TR), which is the annual demand multiplied by the unit price.
c. Based on other consideration, the firm's management will only consider price alternatives of $30, $40, and $50. Use your model from part (b) to determine the price alternatives that will maximize the total revenue.
d. What are the expected annual demand and the total revenue corresponding to your recommended price?
