2. (a) The demand and supply functions of a particular good in a competitive market are defined
respectively as p = 200q
q1 and p = 30+2q. If p and q denote the price and quantity respectively,
determine the equilibrium price and quantity. [15 Marks]
(b) Let the price and quantity functions of a product be given by p = 2x + k and q = x + 2
respectively, where x is a variable and k is a constant. Find the value(s) of k for which the total
revenue function is always positive. [15 Marks
