1. Using the following demand and supply functions answers the following questions.
Qd = 22 - 2p + 0.5Y; Qs = 15 + 4p - 2CI; where Y = income and CI - cost of inputs.
(a) Calculate the equilibrium price and quantity when Y = 30 and CI = 10
(b) What happens to the equilibrium price and quantity if (i) Y increases to 40, (ii) CI increases to 15?
