(a) How many units can be sold at the $30 price?
units
How many units can be sold at the $70 price?
units
(b) Model the expression for total revenue (TR) in terms of $p$.
TR =
(c) Consider prices of $40, $50, and $60. Which of these three price alternatives will maximize total revenue?
$40
$50
$60
What is the value for demand (in units) at this price?
