I need help with the below question kindly provide graphs where necessary for better explanation.

2.29. Consider the following sequence of changes in the demand and supply for cab service in some city. The price P is a price per mile, while quantity is the total length of cab rides over a month (in thousands of miles). January: Initial demand and supply are given by the equa- tions QF = 30P 30 (when P = 1),and Q = 120 20P February: Due to higher prices of gasoline, the supply of cab service changed to Q = 30P 60 (when P = 2). March: Over the spring break, the demand for taxi serv- ice was higher and therefore the demand curve was given by the equation Q = 140 20P. a) For each month find the equilibrium price and quantity. b) Illustrate your answer with a graph. Illustrate the equilibrium prices and quantities on the graph
