1) In the class of 120 students, everybody would take 2 hamburgers if price were zero, and no one would buy hamburgers if te price were $4 or more.
Suppose that class's demand curve for hamburgers is linear, and give a suitable formula
(a) describeing quantity as a function of price
(b) describeing price as a function of quantity
(c) Total revenue is the function of quantity and can be find outd by R = price quantity. Determine the total revenue function corresponding to demand curve, and conclude that it is quadratic.
